Turn Milk into Plastic! Lesson Plan Science Buddies

In a polymer, a single repetition of the pattern of molecules is called a monomer (even if the polymer is made up of only one type of molecule). The process of making a polymer is called polymerization, which describes the transformation of many individual monomer molecules into large chains or three-dimensional networks. There are many types

Styrene Monomer Chevron Phillips Chemical

Styrene is one of the most important monomers produced by the chemical industry today. Styrene monomer is a basic building block of the plastics industry. The conventional method of producing styrene involves the alkylation of benzene with ethylene to produce ethylbenzene, followed by dehydrogenation of ethylbenzene to styrene.

Difference between Plastic and Polymer Plastic vs Polymer

The term 'polymer' is commonly used today in the plastics and composites industry, and it is often used to imply the meaning of 'plastic' or 'resin'. However, the term is just a component which is used to synthesize plastic. A polymer is chemical compound where molecules are bonded together in long repeating chains.

Low-density polyethylene (LDPE) has a similar makeup to HDPE but is more translucent, less chemically resistant and less rigid. LDPE, which has the resin identification code 4, is made from the monomer ethylene and is most commonly used to make plastic bags, but it can also be found in detergent bottles, dispensing bottles, and squeezable bottles for foodstuffs like honey and mustard.
