Abstract
Abstract Shaped articles having improved mechanical strengths are comprised of (i) a nylon polyamide resin, (ii) a reinforcing amount of glass fibers therefor, and (iii) an impact strength increasing amount of a (meth)acrylic compound having the structural formula: [CH2=CR-CO-A]n X (I) wherein R is hydrogen or methyl, n is an integer equal to 2, 3 or 4, A is the linkage -O- or -NH- and X is an organic radical of valency n selected from the group consisting of linear or branched chain alkylene radical having from 1 to 20 carbon atoms, such alkylene radical comprising one or more chain-interrupting oxygen bridges and/or one or more hydroxyl groups, an aralkylene radical wherein the aryl moiety contains from 6 to 10 carbon atoms and the alkylene moiety is as defined above, such aralkylene radical comprising one or more alkylene chain-interrupting oxygen bridges, and a triazino heterocycle.
