Abstract
The variation of tensile strength and elongation at break of styrene-b utadiene-styrene triblock copolymer containing 34.1, 40.0 and 52.5% st yrene have been studied with respect to their morphology and the exten t of crosslinking produced by irradiation with Co-60 rays. We assume t hat the existence of microphase separation between polybutadiene (PB) and polystyrene domains and entanglements between PB segments result i n the unusual variation of the two characteristics with radiation dose , which is different from that in common elastomers and blends.
