    摘要: A toughened multiphase thermoplastic composition is provided by incorporating at least one functionalized, selectively hydrogenated alkenyl arene/conjugated diene block copolymer to which has been grafted an effective amount of carboxyl functional groups primarily in the alkenyl arene blocks thereof with a thermoplastic polyester. The carboxyl functional groups may be in the form of carboxylic acids, their salts, their esters, and combinations of two or more of these.

    摘要: A thermoplastic polymer which possesses excellent mechanical properties at both room and elevated temperatures is obtained by reacting an acyl sulfate with a block copolymer composed of at least one conjugated diene block and one alkenyl arene block. The block copolymer is first selectively hydrogenated and thereafter modified by grafting sulfonic acid functional groups primarily in the alkenyl arene blocks. The mechanical properties may be varied and controlled by varying the degree of functionalization (amount of sulfonation), and the degree of neutralization of the sulfonic acid groups to metal sulfonate salts.

    摘要: The anionic polymerization of unsaturated monomers with functionalized initiators having the structure R.sup.1 R.sup.2 R.sup.3 Si--O--A'--Li is improved by selecting A' from the structures --CH.sub.2 --CH.sub.2 --CH.sub.2 -- (1,3-propyl), --CH.sub.2 --CH(CH.sub.3)--CH.sub.2 -- (2-methyl-1,3-propyl), --CH.sub.2 --C(CH.sub.3).sub.2 --CH.sub.2 --(2,2-dimethyl-1,3-propyl), or --CH.sub.2 --CH.sub.2 --CH.sub.2 --CH.sub.2 --CH.sub.2 --CH.sub.2 --CH.sub.2 --CH.sub.2 --(1,8-octyl). This narrow class of polymerization initiators operate at surprisingly higher polymerization temperatures with surprisingly lower amounts of dead initiator than similar initiators wherein A' is --CH.sub.2 --CH.sub.2 --CH.sub.2 --CH.sub.2 --(1,4-butyl), --CH.sub.2 --CH.sub.2 --CH.sub.2 --CH.sub.2 --CH.sub.2 --(1,5-pentyl), or --CH.sub.2 --CH.sub.2 --CH.sub.2 --CH.sub.2 --CH.sub.2 --CH.sub.2 --(1,6-hexyl).
