FIBER-CONTAINING ALIPHATIC POLYESTER RESIN COMPOSITION AND METHOD FOR PRODUCING THE SAME

PROBLEM TO BE SOLVED: To prevent cellulosic fibers from being made short fibers, to inhibit aggregation of cellulosic fibers in a biodegradable resin, and to obtain a high-strength and high-rigidity fiber-containing aliphatic polyester resin composition. SOLUTION: The fiber-containing aliphatic poly...

Zusammenfassung:PROBLEM TO BE SOLVED: To prevent cellulosic fibers from being made short fibers, to inhibit aggregation of cellulosic fibers in a biodegradable resin, and to obtain a high-strength and high-rigidity fiber-containing aliphatic polyester resin composition. SOLUTION: The fiber-containing aliphatic polyester resin composition comprises 1-99 pts.wt. of at least one aliphatic polyester resin (A) selected from aliphatic polyesters each obtained by reacting an aliphatic diol with an aliphatic dicarboxylic acid and/or a derivative thereof, and poly(oxycarboxylic acids), 1-20 pts.wt. of a polymer dispersant (B) having a weight average molecular weight of 1,000-100,000, and 98-1 pt.wt. of cellulosic fibers (C).
