Abstract: Disclosed is a thermoplastic melt-mixed composition including: a) a polyamide resin; b) 0.50 to about 5.0 weight percent of one or more amino acid selected from the group consisting of primary amino acids and secondary amino acids; said amino acid having no hydroxyl groups and no more than one carboxylic acid; optionally, c) one or more polyepoxy compound including at least two or more epoxy groups; d) reinforcing agent; e) polymeric toughener; and f) further additives; wherein the weight percents of components a), b), c) d) e) and f) are based on the total weight of the thermoplastic melt-mixed composition. Also disclosed are processes for making the compositions.

Abstract: Disclosed is a thermoplastic melt-mixed composition having a melt viscosity provided by melt-blending components including: a) a semi-crystalline polyamide resin having a melting point; b) one or more polyepoxy compound including at least two or more epoxy groups; c) one or more amino compounds selected from the group consisting polyamines and amino alcohols, and combinations of these, d) reinforcing agent; and optionally e) polymeric toughener; and f) further additives. Also disclosed are specific processes for preparing the thermoplastic compositions and molded parts derived from the thermoplastic compositions.

Abstract: Disclosed is a thermoplastic melt-mixed composition including: a) a semicrystalline polyamide resin; b) a polyepoxy compound including at least two or more epoxy groups; the polyepoxy compound having a number average molecular weight of less than 8000; one or more carboxylic acid compounds selected from the group consisting of polyacids, acid alcohols and combinations of these, the carboxylic acid compounds have a number average molecular weight of less than 2000; and optionally, d) reinforcing agent; e) polymeric toughener; and f) further additives.
