Grafted modified styrene elastomers and curing compositions

Abstract

The grafted styrene-based elastic system of the present invention is obtained by grafting and modifying aromatic vinyl monomers without polar groups. In the grafted styrene-based elastomer, the grafting rate of the aromatic vinyl monomer is 0.5% by mass or more. Preferably, the grafting rate of the aromatic vinyl monomer is 10.0% by mass or less. The curing composition comprises a base material and a grafted styrene-based elastomer. The base material preferably comprises polyphenylene ether.
