Polymers and Polymerization
Different plastics will have different rates of shrinking as well as heat/curing rates. For polymerization to occur the material has to have the right molecules. Each molecule is made up of ethylene monomer. Monomer means one part. Each synthetic build block is fused together during polymerization. Ethylene in a tiny hydrocarbon made up of four hydrogen atoms and two carbon atoms. The monomers are combining with a catalyst. A catalyst aids in the chemical reaction that occurs in the material. It usually doesn’t undergo any change its self. During polymerization the monomers make long complex chains. These chains are called polymers. The polymers are able to o keep their plastic properties once cooled.
Plastics are polymers, but not all polymers are plastics. Plastics are man made to imitate natural polymers. Cellulose found in celery as long crunch strings is a natural polymer. These molecules are found in the cell walls of the plant. Another type of polymer is cotton, silk and wool. These products have inspired scientists to replicate them. Polymers are super strong and can have liner chains or cross linked chains. Each polymer is different but can be used for similar jobs.
