Polybutylene (polybutene-1, poly(1-butene), PB-1) is a polyolefin or saturated polymer with the chemical formula (CH 2 CH(Et)) n. Not be confused with polybutene , PB-1 is mainly used in piping. [ 2 ]
Polybutylene succinate (PBS) (sometimes written polytetramethylene succinate) is a thermoplastic polymer resin of the polyester family. PBS is a biodegradable aliphatic polyester with properties that are comparable to polypropylene. It may also be referred to by the brand names GsPLA or BioPBS (Mitsubishi Chemical). [1]
Polybutylene terephthalate (PBT) is a thermoplastic engineering polymer that is used as an insulator in the electrical and electronics industries. [2] It is a thermoplastic (semi-)crystalline polymer , and a type of polyester .
Polybutene is an organic polymer made from a mixture of 1-butene, 2-butene, and isobutylene.Ethylene steam cracker C4s are also used as supplemental feed for polybutene. It is similar to polyisobutylene (PIB), which is produced from essentially pure isobutylene made in a C4 complex of a major refinery.
Butene, also known as butylene, is an alkene with the formula C 4 H 8.The word butene may refer to any of the individual compounds. They are colourless gases that are present in crude oil as a minor constituent in quantities that are too small for viable extraction.

A polyolefin is a type of polymer with the general formula (CH 2 CHR) n where R is an alkyl group. They are usually derived from a small set of simple olefins . Dominant in a commercial sense are polyethylene and polypropylene. More specialized polyolefins include polyisobutylene and polymethylpentene. They are all colorless or white oils or ...
