TRANSPARENT SEMI-INTERPENETRATING NETWORK COMPRISING A PHASE OF A LINEAR, NON-CROSSLINKED ISOBUTENE POLYMER

摘要

A transparent, semi-interpenetrating network comprises a first phase of a linear noncrosslinked isobutene polymer and a second phase of a crosslinked polymer. The crosslinked polymer is obtained through copolymerization of a first ethylenically unsaturated monomer and of a second ethylenically unsaturated monomer, wherein the first ethylenically unsaturated monomer is a cycloalkyl(meth)acrylate and the second ethylenically unsaturated monomer is selected from linear and branched C₁-C₂₀ alkyl(meth)acrylates. By varying the ratio of the first ethylenically unsaturated monomer relative to the second ethylenically unsaturated monomer, the properties, such as vibration damping properties, of the semi-interpenetrating network can be controlled.
