Abstract
Use of masterbatches of polyarylene amides in polyester resins containing from 10 to 40% by weight of polyamide resin in the preparation of mixtures of aromatic polyester rensins added with the polyamide resin at a concentration of less than 15% by weight.
Claims7
Use of masterbatches of polyarylene amides in aromatic polyester resins containing from 10 to 40% by weight of polyarylene amide and in which the polyarylene amide is dispersed uniformly in the polyester matrix in the form of domains with average numeral size of less than 1 micron, in the preparation of aromatic polyester resins to which polyarylene amides are added and in which the polyamide is present at a concentration of less than 15% by weight.
