STYROLUX(- FROM TRANSPARENT HIGH-IMPACT POLYSTYRENE TO NEW THERMOPLASTIC ELASTOMERS - SYNTHESES, APPLICATIONS AND BLENDS WITH OTHER STYRENEBASED POLYMERS() AND STYROFLEX(+) )

Styrolux and Styroflex are styrene and butadiene based block copolymer s prepared by butyllithium initiated anionic polymerization. Styrolux is a transparent, tough and stiff thermoplastic material for high spee d processing. Its specially designed molecular structure allows homoge neous mixing with general purpose polystyrene maintaining the transpar ency. Styroflex is a newly commercialized product with the mechanical behavior of a thermoplastic elastomer, e.g. low modulus and yield stre ngth, high elongation and excellent recovery. High transparency and th ermal stability give the competitive edge over conventional styrene-bu tadiene elastomers. Styroflex, Styrolux and general purpose polystyren e form a unit construction system e.g. for transparent film materials and injection molded parts with fine-tunable hardness and toughness.
