Abstract

When styrene-butadiene-styrene (SBS) block copolymers are chemically cross-linked and subsequently converted to semi or full interpenetrating networks (IPNs) by the in situ polymerization of styrene, transparent tough products can be made. The process is complicated by changes in block copolymer morphology, grafting reactions and the form of interpenetration that the polystyrene takes within the thermoplastic elastomer continuous phase. Here, changes in morphology during IPN production are monitored by transmission electron microscopy, and associated thermal behaviour shown by dynamic mechanical analysis. In tough products, changes in domain structure in the SBS occur, together with an increased miscibility between the SBS and PS.
