Blends of styrene-butadiene-styrene triblock copolymer with random styrene-maleic anhydride copolymers [PDF]
Macromolecular Chemistry and Physics, 2002 Blends of styrene-butadiene-styrene triblock copolymer (SBS) with random styrene-maleic anhydride copolymers (PS-co-MA), having different MA content, were prepared in a Brabender Plastigraph mixer. The presence of polystyrene (PS) blocks in the SBS copolymer and the high styrene content (93 and 86 wt.-%, respectively) in the two kinds of used PS-co-MA ...

Blood styrene and urinary metabolites in styrene polymerisation. [PDF]
Occupational and Environmental Medicine, 1978 The results of the analysis of blood and urine samples for styrene and its metabolites in 491 workers in a styrene polymerisation plant in the United States are reported. The levels of exposure to styrene were estimated to be less than 10 ppm, but nevertheless styrene and metabolites were detectable in more than 50% of workers in polymerisation jobs ...
