COMPOSICOES DE MOLDAGEM BASEADAS EM POLIESTER

摘要

Described are molding compositions endowed with high rates of crystallization and suitable for molding at mold temperatures not higher than 100 DEG C and resulting in molded articles having an optimum combination of mechanical, physical and thermal properties and of surface appearance, comprising a preferably linear and saturated polyester; a salt of a mono- or polycarboxylic acid; an ionomer copolymer containing pendant carboxylic groups which are at least partially salified; and a solid inert inorganic substance having a particle size not higher than 5 mu m. Said compositions may be reinforced, preferably by glass fibers.
