Quick Summary

Heterochain polymers are polymers where the main chain includes elements like oxygen, nitrogen, sulfur, or silicon, in addition to carbon. These polymers have diverse structures and are widely used commercially.1234

Key types of heterochain polymers include:

Polyesters: Formed through condensation reactions creating ester groups. Major industrial examples are polyethylene terephthalate, polycarbonate, and degradable polyesters like polylactic acid (PLA).12
Polyethers: Polymers linked by ether (C-O-C) groups. Examples include high-strength plastics like polyetherketone (PEK) and polyetheretherketone (PEEK), known for their thermal stability and chemical resistance. Polyphenylene oxide (PPO) is another example, often blended with polystyrene for enhanced properties.34

Degradable polyesters, such as PLA, are of interest for medical applications and biodegradable packaging due to their breakdown into natural metabolites. Unsaturated polyesters are used in reinforced products like boat hulls and automotive parts.12

major industrial polymers
…polymers (also called vinyls) or heterochain polymers (also called noncarbon-chain, or nonvinyls). In carbon-chain polymers, as the name implies, the backbones are composed of linkages between carbon atoms; in heterochain polymers a number of other elements are linked together in the backbones, including oxygen, nitrogen, sulfur, and silicon.
