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 .
Sensicrystal (Sensient Cosm) (Polybutene
with trade name Indopol PB L-6 and number-average molecular mass 280 was supplied by INEOS Oligomers Inc.
and polyisobutylene are generally used where extraction resistance is required, such as in brake fluid applications.
 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.
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.
