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. 95ΠC. Tear strength at high temperatures can be improved by slight crosslinking of P
## Abstract The oxidation behavior of emulsion isoprene/styrene copolymer (SIR) and emulsion butadiene/styrene copolymer (SBR) by heat aging of ultraviolet irradiation in air has been investigated from the change of gel fraction, intrinsic viscosity, molecular weight distribution, and mechanical pr
