Polymer Journal #4



Prototype 1 had a softer feeling, since there was much less borax solution, which felt very good and comfortable on the grip of the club, but had an extremely short “life span” of two days. Prototype 2 on the other hand had a slightly harder touch, but it could last for longer periods of time.

The reasons why the polymer has to last for a long period of time is because, it would have to compete against the current golf grip brands that last for a sufficient 2-3 years. Prototype 2 was more efficient in meeting our goal. Although it wasn’t as comfortable as Prototype 1, it felt better than an average golf club grip. Also throughout this whole project it lasted perfectly meaning that it can last for a long time. Overall throughout the project the goal of our product was successfully fulfilled. We wanted a comfortable golf grip which could last for a long period of time.

Although the final result wasn’t exactly what we were expecting, since we were expecting a fancier design on the polymer, and perhaps a much larger amount rather than just on your hand. Also at the beginning of the project we were trying to make a polymer that would cove the entire grip, but later we figured that there would be a more sufficient way to have the same effect. This was by having the polymer on your hand, so what the player would be feeling will be soft. I learnt throughout this project, many things about the polymers we were dealing with, I noticed that the polymers could substitute for many objects that we come across in daily life.

A good golf club is defined by the quality of its shaft, head, but mainly its grip. We want the grip to be soft and squishy, to make the contact with the ball smooth, also it has to last for at least 3 days, to be marked as an efficient prototype.

For this to take place we will need to combine the quality of the Gloop, which gives the squishiness, and Stretch-tastic to make it stick. The Gloop is not sticky, but is very soft, which gives me the soft characteristics. The goal of our polymer is to have a golf club grip, which is soft, and able to stick onto the shaft of the club. Due to Stretch-tastic’s sticky physical characteristics, it would serve as the scotch tape, which sticks the gloop to the shaft. The Gloop, has a soft and not-sticky physical characteristic. This makes the gloop good to substitute for the cushiony material which was used to make the grip soft. When we combine the two polymers together we will get a grip that can stick to the shaft of the club, and is soft.

We can test the grip by sticking in on one of the clubs that I no longer use (3 Wood: The club is too heavy for me) and put the grip that we made on. I will later swing the club gently on the grass beside the field in ISB, I will then analyze the feeling. After 3 test runs, if my hand is not sore, or tired it means that our Polymer had succeeded.

My goal in this polymer project is to design a soft and durable grip for a golf club that won’t give the player blisters, and pain in the finger. As my product is the grip for a golf club, I would be targeting my product for golfers who play for longer duration. During an average golf tournament, which lasts for two days, golfers must walk for unimaginable durations of time, while swinging a heavy piece of iron (golf club). Many professionals and even amateurs began to experience large swells on the palms of their hand. This is due to the large amounts of swings they take, causing their hands to rub against a bare piece of think rubber like material. Also, if a player plays for too long, their nails begin to tear from the top of their fingers. With a softer grip, these problems can be solved. The soft grip would provide a soft touch to the swing. I believe the gloop will be the best for my product. The gloop has many characteristics that we are looking for. It is soft, it is stretchy, and it molds in to the shape that you press it into and stays like that for a long time, unlike an ordinary grip on clubs, made of think rubber, and a rough surface.

My authentic client would definitely be my father. He is a fine golfer, but can’t manage over 18 holes, since his hands begin to blister and cuts open up. With the soft and stretchy polymer as a grip, these problem won’t occur anymore, and I would be able to play more and more often with him.

Monomers join bonds and form polymers. Monomers are molecules of any of a class of compounds, mostly organic, that can react with other molecules to form very large molecules, or polymers. The polymers have a natural resource and synthetic materials. Natural resources are resources that exist without actions of humankind, some Natural Resources Are Sunlight, and water. Synthetic materials are made from chemicals and are usually based on polymers. They are stronger than natural and regenerated materials, some examples are Artificial Turf, and Synthetic Fabrics. Natural Resources have biotic and abiotic factors, such as biotic can be fossil fuels while abiotic could be eco-friendly energy sources. When natural resources go through a chemical reaction to become synthetic materials, the Monomer goes through polymerization, joining with other molecules, to form a larger molecule, that contain repeating structural units.  Two examples of Synthetic Polymer is Nylon and Plastic. Nylon comes from oil, petrol, air and water, it is as a replacement for silk and rubber, since it is stronger. Plastic comes from carbon, hydrogen, oxygen, nitrogen, chlorine, and sulfur, plastic is found almost everywhere, from a plastic bottle, to things that you rely on for everyday life, these plastics are bad for the environment, but makes life for you very convenient. Polymerization is chemical reaction in which two or more molecules combine to form larger molecules that contain repeating structural units
