The polymers are linear and therefore are solid. The monomers are mainly arranged head-to-tail, indicating that chloride is situated on alternating carbon centres. PVC has mainly an atactic stereochemistry, which suggests the relative stereochemistry of your chloride centres are random. Some degree of syndiotacticity from the chain provides a number of p.c crystallinity that is definitely influential over the Qualities of the material.
