Provided is a method of making a polymeric composition comprising (a) providing a dispersion of initial polyolefin particles in an aqueous medium, wherein the initial polyolefin particles comprise (i) one or more hydrocarbon polyolefin, (ii) one or more non-hydrocarbon polyolefin, and (iii) one or more crosslinking agent; (b) contacting the initial polyolefin particles with a peroxide initiator to form crosslinked polyolefin particles.

Provided are a film and an electric device comprising the same. The film comprises at least one modified polyolefin resin layer. A resin forming the modified polyolefin resin layer comprises 1-100% of modified polyolefin resin. A main chain in the modified polyolefin resin is an ethylene-α-olefin copolymer. A grafted branched chain in the modified polyolefin resin is selected from a compound formed by a vinyl monomer comprising one or more of anhydride group, hydroxyl, ester group, carbonyl, acylamino, pyridyl, epoxy, pyrrolidonyl and glycidyl. A molecular weight of the grafted branched chain is 150-8000 g/mol. The film prepared from the modified POE layer with the main chain and the grafted branched chain has excellent anti-PID performance. The layers have a better adhesive property without a laminated interface therebetween. The co-extruded film further has an excellent water vapor barrier property, a relatively high insulating property and a relatively high light transmittance.

Disclosed are single step and multi-step methods of making functional polyisobutylene (PIB)-containing oligomers and polymers and the materials made thereby. In the single step method a functional group containing PIB oligomer or polymer is made under cationic polymerization conditions in a direct, one step reaction. In the multi-step method a functional group containing PIB oligomer or polymer is made in a two-step process. The first step is performed under cationic polymerization conditions. The second step is performed under non-cationic polymerization conditions.
