Bojkova et al. (4) prepared high-impact poly(urethane-urea) polysulfides having a refractive index of at least 1.57, an Abbe number of at least 32, and a density >1.3g/cm2 3, which consisted of the reaction product of... [Pg.520]

On the other hand, high impact poly(styrene) (HIPS), ABS, acrylonitrile-ethylene-propylene-based rubber/styrene copolymer resin (AES), acrylonitrile/acryl-based rubber/styrene copolymer resin (AAS) show excellent impact strengths, but these resins are inferior in chemical resistance and abrasion resistance. [Pg.222]

High impact poly(styrene) (HIPS) is sometimes also accessed as TPS, which stands for toughened PS. [Pg.269]

Various patents on the homopolymerization of BD in the presence of styrene are available [581-590]. According to these patents, St is used as a solvent in which BD is selectively polymerized by the application of NdV/DIBAH/EASC. At the end of the polymerization a solution of BR in St is obtained. In subsequent reaction steps the unreacted styrene monomer is either polymerized radically, or acrylonitrile is added prior to radical initiation. During the subsequent radical polymerization styrene or styrene/acrylonitrile, respectively, are polymerized and ris-l,4-BR is grafted and partially crosslinked. In this way BR modified (or impact modified) thermoplast blends are obtained. In these blends BR particles are dispersed either in poly(styrene) (yielding HIPS = high impact poly(styrene) or in styrene-acrylonitrile-copolymers (yielding ABS = acrylonitrile/butadiene/ styrene-terpolymers). In comparison with the classical bulk processes for HIPS and ABS, this new technology allows for considerable cost reductions... [Pg.98]

As mentioned extensively, PPE is not mainly used as such, but in polymeric blends and copolymers to faciUtate the fabrication. Some of these copolymers act also as impact modifiers for example, block copolymers built from styrene, ethylene, butylene, and propylene. Naturally, the impact can be improved by using high impact poly(styrene) (HIPS) instead of ordinary PS in blends. Other impact modifiers include rubbery materials, such as poly(octenylene), and ethylene propylene diene monomer rubber. [Pg.154]
