Relationship of Morphology to Physical Properties of Styrene-Butadiene Block Copolymers
Conference paper
Abstract
Block copolymers of the type polystyrene-polybutadiene-polystyrene (SBS) behave like reinforced vulcanized elastomers at room temperature.1–3 The addition of low molecular weight polystyrene adds further reinforcement. (For example, this addition to a SBS polymer of 30 wt. % styrene to give an overall composition of 40 wt. % styrene increased the modulus at an extension ratio of 5 from 23 to 44 kg. /cm.2 at a strain rate of 31.5 min.−1)
