Abstract

PURPOSE: To modify a composition containing a linear saturated polyester and an inorganic filler into a composition having a reduced carboxyl group content, excellent heat resistance, hydrolysis resistance and mechanical properties, by reacting the starting composition in the molten state, with a compound having a specific structure.
CONSTITUTION: One tenth to ten (0.1W10)wt%, based on resin composition, of a compound of formula I, wherein X and D are bivalent organic groups, n is 1 or 2 and the ring structure of formula II is five-membered or six-membered, such as 2,2'- bis(2-oxazoline) or 2,2'-bis(5,6-dihydro-4H-1,3-oxazine), is added to a polyester resin composition comprising a substantially linear saturated polyester and 5W 10wt%, based on the resin, of an inorganic filler, such as a resin composition prepared by adding glass fibers to, for example, polyethylene terephthalate, in any stage before molding the composition. Then, the resulting mixture is reacted in the molten polyester. Thereby, the polymerization degree of the resin composition is increased and the terminal carboxyl group content is lowered.
