Polybutene is a polymer which is derived from isobutylene.
It is possible to protect
polybutene piping and acetal fittings against the known risks of oxidation, and this is done in Europe, where such plumbing is used extensively.
Carboxylic acid alkoxylates together with
polybutene amines act in a similar manner [48].

Polybutene with trade name Indopol PB L-6 and number-average molecular mass 280 was supplied by INEOS Oligomers Inc.
Polybutene and polyisobutylene are generally used where extraction resistance is required, such as in brake fluid applications.
[15] studied the thermo-oxidative stability of
polybutene pipes using hydrostatic pressure aging and reported that the pipe material degradation was initiated at the outer surface of the pipe and the molecular weight of the polymer decreased upon depletion of the antioxidant.
As the weight loss for the PLTC compound is in fact less than that for the control compound, then any loss of
polybutene must be minimal.
Polybutene improves impact resistance of many thermoplastics, including crystal PS, high-impact PS, PP homopolymer, and elastomer-modified PP.
This agent works especially well for polyolefins such as polypropylene, polyisobutylene,
polybutene, poly-4-methylpentene, and polyethylene.
