ChEBI: A polymer composed of repeating 1,1-dimethylethylene units. | [Application]
Polyisobutylene (PIB) is a vinyl polymer with a uniquely low water diffusion rate and low glass transition temperature (Tg) (-75 °C). It is widely available for use in the following ways:
(1) PIB can be used as a common encapsulation material for photovoltaic modules.
(2) Chemically inert elastomers with oxidation and thermal degradation resistance and low gas permeability.
(3) Plasticisers in rubber formulations and sporting goods (e.g. golf clubs, tennis rackets, grips for bicycles and tools).
(4) Adhesive compositions used as wound dressings where PIB acts as a tackifier.
(5) Functionalisation of polyisobutylene with pyrene by photoinduced radical addition of 1-bromomethylpyrene in the presence of Mn2(CO)10 during the preparation of polyisobutylene-based block copolymers.
(6) Highly reactive polyisobutylene (HRPIB) is the most important industrial polymer material used as a lubricant, fuel and polymer additive. In contrast to conventional Polyisobutylene, HRPIB is a polymer using olefins as end groups. | [Preparation]
Silicone rubbers are prepared as follows:
Other groups may replace the methyl groups. Silicone rubbers have excellent ozone and weathering resistance, good electrical properties, and good adhesion to metal. | [Solubility in organics]
