Polymer Journal #4

Prototype #1 was named “The Great Mistake” because it was created when we accidentally mixed PVA Glue with Borax. It was very bouncy but it was a little to hard, so it didn’t meet our goal.

Prototype #2 was when we added Guar Gum and more Borax to our prototype. It met our goal of being the top layer of our shoe pad because it was flexible and strong. However, we need something bouncier for our middle layer. So we moved on to prototype 3.

Prototype #3 was when we added PVA Glue to Guar Gum and Borax and PVA Solution. We had a thin white soft bouncy and stretchy layer. We decided to use this as our middle layer.

Prototype #4 was originally a failure, we smashed prototype 2 and 3 together, but it ended up as a messy lump. However, after we left it in an airtight bag after 4 days, it became just what we wanted. Somehow, when it was in that bag, the chemicals reacted and combined into the perfect polymer. It was soft, flexible, and bouncy. However it was easily broken.

Prototype #5 was just like #4, but we added more borax. After that it was a little bit bouncier. This prototype met our goal because it had a medical impact on the foot. It is beneficial to the foot health.

In conclusion I have learned that sometimes, we don’t always get what we want, but when accidents occur and we do get we want, we should grasp that opportunity.

Polymer Project 3

Currently, we are making a polymer that has a medical purpose. So we made a shoe pad. We need a shoe pad that is soft, flexible, but strong. In order to make this polymer, we added the NVA Glue and Borax, and Guar Gum, plus Harry’s other mistake, and we left it in an airtight bag overnight. In order to test the quality, we will wear it and test it why running with it. This will see if it breaks or not and we can guarantee the quality.img_1487 img_1490 img_1491 img_1492

Synthetic materials.made by chemical synthesis, especially to imitate a natural product: synthetic rubber. Natural resources are materials or substances such as minerals, forests, water, and fertile land that occur in nature and can be used for economic gain. Two examples of synthetic materials are rubber and plastic, while two examples of natural resources are oil and water. Polymers are a substance that has a molecular structure consisting chiefly or entirely of a large number of similar units bonded together, e.g., many synthetic organic materials used as plastics and resins. A polymer is a substance that has a molecular structure consisting chiefly or entirely of a large number of similar units bonded together, e.g., many synthetic organic materials used as plastics and resins. An example of a synthetic material is plastic, we use this for nonreusable bottles. First, let me explain what polymerization is, polymerization is to combine multiple monomers to form one big polymer.
