Abstract

A resin composition contains (A) a polylactic acid, (B) a polyhydroxyalkanoate, (C) an ammonium polyphosphate, and (D) a phenol-modified epoxy compound. With respect to the total amount of the resin composition, the polylactic acid (A) and the polyhydroxyalkanoate (B) are contained from about 60% by mass to about 95% by mass; the ammonium polyphosphate (C) is contained from about 4% by mass to about 35% by mass; the phenol-modified epoxy compound (D) is contained from about 1% by mass to about 5% by mass; the polylactic acid (A) is contained from about 40% by mass to about 90% by mass; the polyhydroxyalkanoate (B) is contained from about 5% by mass to about 55% by mass; and the amount ratio of the polylactic acid (A) to the polyhydroxyalkanoate (B) is from about 0.7 to about 18.

Claims (36)

1. A resin composition comprising:

(A) a polylactic acid,

(B) a polyhydroxyalkanoate,

(C) an ammonium polyphosphate, and

(D) a phenol-modified epoxy compound,

wherein the polylactic acid (A) and the polyhydroxyalkanoate (B) are contained in an amount of from about 60% by mass to about 95% by mass with respect to the total amount of the resin composition;

the ammonium polyphosphate (C) is contained in an amount of from about 4% by mass to about 35% by mass with respect to the total amount of the resin composition;

the phenol-modified epoxy compound (D) is contained in an amount of from about 1% by mass to about 5% by mass with respect to the total amount of the resin composition;

the polylactic acid (A) is contained in an amount of from about 40% by mass to about 90% by mass with respect to the total amount of the resin composition;

the polyhydroxyalkanoate (B) is contained in an amount of from about 5% by mass to about 55% by mass with respect to the total amount of the resin composition; and

the amount ratio of the polylactic acid (A) to the polyhydroxyalkanoate (B) is from about 0.7 to about 18.

2. The resin composition according to claim 1 , wherein the polyhydroxyalkanoate is a copolymer of polyhydroxybutyrate and polyhydroxyhexanoate.

3. The resin composition according to claim 1 , wherein the weight-average molecular weight of the polylactic acid is from about 30,000 to about 260,000.

4. The resin composition according to claim 2 , wherein the weight-average molecular weight of the polylactic acid is from about 30,000 to about 260,000.
