It has been found that SBS block copolymers possess excellent tear strength at room temperature. However, tear strength is virtually zero at temperatures higher than the glass transition temperature of PS phase, ca. 95ЊC. Tear strength at high temperatures can be improved by slight crosslinking of P
## Abstract This work pertains to the development of high strength elastomers potentially useful as nonthrombogenic cardiovascular prostheses. Triblock copolymers of the styrene–butadiene–styrene type have been subjected to surface hydroxylation which provide reactive sites at the surface for the s
