WebPolymers are long chain, giant organic molecules are assembled from many smaller molecules called monomers. Polymers consist of many repeating monomer units in long chains, sometimes with branching or cross-linking between the chains. An addition polymer is a polymer which is formed by an addition reaction, where many monomers bond … WebWorld Plastics Materials Demand 2015 by Types • Polyolefins account for more than 55% of global Plastics Materials demand. • PVC is the second largest resin
