Abstract
Polymers are obtained by polymerizing in the presence of a Bronsted acid or a Lewis acid catalyst, a monomer comprising a 1,3-diisoalkenylarene, a 1,4-diisoalkenylarene, or mixtures thereof. The polymer comprises at least one of repeat units (A), (B), (C), and (D); wherein Ris H or a C1-C8 alkyl group. The polymers have high Tand exhibit good solubility in non-polar solvents, forming substantially gel-free solutions. The polymers are useful for producing crosslinked materials having good physical properties. The crosslinked materials are valuable for further downstream uses, such as copper clad laminates.
