The polymers are linear and so are powerful. The monomers are mostly organized head-to-tail, that means that chloride is situated on alternating carbon centres. PVC has predominantly an atactic stereochemistry, which implies that the relative stereochemistry of the chloride centres are random. Some degree of syndiotacticity with the chain presents a couple of percent crystallinity that may be influential to the properties of the material.
About 50 percent of the whole world's PVC output capacity is in China, despite the closure of many Chinese PVC plants on account of difficulties complying with environmental restrictions and weak capacities of scale.
