polyisobutene (hydrogenated) bụ ihe na-eme ka ihe dị nro.
Polyisobutylene, nke a na-akpọ mgbe ụfọdụ butyl roba, na mgbe ụfọdụ PIB, bụ vinyl polymer. O yiri nke polyethylene na polypropylene n'ụdị ya, ma e wezụga na a na-eji otu methyl abụọ dochie carbon ọ bụla ọzọ. E ji monomer isobutylene mee ya, site na cationic vinyl polymerization.
Polyisobutylene bụ rọba sịntetik, ma ọ bụ elastomer. Ọ pụrụ iche n'ihi na ọ bụ naanị rọba nke gas na-anaghị agbapụta. Ya bụ, ọ bụ naanị rọba nwere ike ijide ikuku ruo ogologo oge.
