Polybutene (polybutylene) (PB) is manufactured by stereospecific ZieglerNatta polymerization of l-butene: Polybutene is generally water-white, reaching less than 50 on APHA color scale. The chemical formula of polybutylene succinate is (C8H12O4) n and its melting point is 1.26 g/cm3. Keywords Polybutene-1 CAS No. Polybutene is a non-polar hydrocarbon polymer hence it has high solubility in aliphatic, aromatic and chlorinated solvents. No gross or microscopic pathological changes could be COrrelated with Polybutene ingestion. Polybutene adds gorgeous, cushiony richness to lip formulations, making them feel more expensive and substantial. Polybutene can shrink more if it is cooled down further or subject to greater pressure. This has a natural stretch similar to Lycra and can be incorporated into sportswear. 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.
