Compare with Definitions

Polyolefin

A polyolefin is a type of polymer with the general formula (CH2CHR)n. They are derived from a handful of simple olefins (alkenes).

Polyurethane

Polyurethane (often abbreviated PUR and PU) is a polymer composed of organic units joined by carbamate (urethane) links. In contrast to other common polymers such as polyethylene and polystyrene, polyurethane is produced from a wide range of starting materials (monomers) and is therefore a class of polymers, rather than a distinct compound.

Polyurethane

(organic chemistry) Any of various polymeric resins containing urethane links; used in very many industrial and domestic applications.

Polyurethane

Any polymer containing [-NH.CO.O-] linkages; such polymers are much used as the basis of light but rigid foams for packaging (polyurethane foam) and for hard coatings, as on floors.

Polyurethane

Any of various polymers containing the urethane radical; a wide variety of synthetic forms are made and used as adhesives or plastics or paints or rubber
