Polymers are molecules that are chemically bonded together to form a long, repeated chain. All polymers start with a base, called the backbone. There are also pendant groups that hang loose or connect chains together. A chemical bond is what holds the atom chains together. In class, we made slime using PVA glue and borax. When borax / laundry detergent is added to the PVA, it changes the position of molecules in a process called cross linking and forms chains- which is the slime.
Synthetic polymers are human-made polymers. Some examples are Nylon and Rubber, yet these are made from natural resources such as tree latex and petroleum oil. To make these natural resources into the polymers, polymerization (combining molecules), heating and spinning, and lastly manufacturing.
