Markush Class. [dubious discuss] Because of its crystalline structure and high molecular weight, PB-1 has good resistance to hydrostatic pressure, showing very low creep even at elevated temperatures. The compound can be manufactured to various viscosity grades to suit the specific process conditions and polymerization reaction, thus making it a highly versatile chemical. Polybutene is prepared from a mixture of butene isomers, which share the same molecular formula (C4H8) but vary in the connectivity of the four carbon atoms and the location of a single carbon-carbon double bond. It is a member of the polyester family of polymers. According to CTFA (2006b), laboratory tests with approved surrogate systems/animals revealed that skin contact testing showed only slight irritation (primary dermal irritation score [PDIS] of 1.5/8.0). The average molecular weight is 500 to 5500.
