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
Specimens of styrene-butadiene-styrene (SBS) block copolymers, Kraton D-1102, were prepared by solution casting using three different solvents: toluene, cyclohexane, and a mixture of tetrahydrofuran and methyl ethyl ketone (THF/MEK). Measurements of fracture energies of SBS specimens were carried ou
