Polybutene can shrink more if it is cooled down further or subject to greater pressure. Toward single-material multifunctional sandwich structures. You may need to do some re-formulating rather than doing a straight one-for-one swap; you might consider adding some lanolin to get a bit of the tacky richness youll be missing from the polybutene. Indopol polybutenes are synthetic hydrocarbon polymers made by polymerization of C4 olefins (primarily isobutene) and are available in a wide range of viscosities. As is well known from cracker-based chemistry, cationic chain polymerization of isobutene yields the homopolymer polyisobutene (PIB), while copolymerization of about 98% isobutene with about 2% isoprene yields butyl rubber. Polybutenes mainly differ from each other in terms of their molecular weight andviscosity.
