    摘要: This invention relates to graft polymers produced from:(1) an elastomer component having glass transition temperatures below 0.degree. C. as the graft base; and(2) graft monomers corresponding to the following general formula: ##STR1## wherein R.sup.1 represents H or a C.sub.1 -C.sub.4 alkyl radical;R.sup.3 represents H, phenyl or a C.sub.1 -C.sub.8 alkyl radical;R.sup.2 represents H, a C.sub.1 -C.sub.10 alkyl or C.sub.6 -C.sub.12 aryl radical or --OR.sup.4 ; andR.sup.4 represents C.sub.1 -C.sub.8 alkyl or C.sub.6 -C.sub.12 aryl optionally substituted by alkyl groups, O-containing or N-containing groups;X represents a single bond, a C.sub.1 -C.sub.10 alkylene or C.sub.6 -C.sub.12 arylene radical, ##STR2## Y represents --O--Z--, --NH--Z--; and Z represents a C.sub.1 -C.sub.10 alkylene or C.sub.6 -C.sub.12 arylene radical; and, optionally, other olefinically unsaturated monomers.

    摘要: The toughness of polybutylene terephthalate can be considerably improved by the addition of an ABS-graft copolymer having a relatively high content of graft base and a closely defined particle size; the typical properties of polybutylene terephthalate, such as its high dimensional heat stability, hardness and rigidity, are not substantially reduced. The products show an excellent multiaxial impact strength.
