Abstract
A resin composition includes an aliphatic polyester; a second polymer compound other than the aliphatic polyester; and an organic phosphoric acid compound that has a phosphorus content of about 20% by mass or more.
Claims12
A resin composition comprising:
- an aliphatic polyester;
- a second polymer compound other than the aliphatic polyester;
- and
- an organic phosphoric acid compound that has a phosphorus content of about 20% by mass;
- wherein
- the aliphatic polyester and the second polymer compound have a molecular weight distribution satisfying a condition represented by a following equation (1):
- Mw(1)/Mn(1)≧Mw(2)/Mn(2) (1)
- wherein
- Mw(1) and Mn(1) represent a weight average molecular weight and a number average molecular weight of the aliphatic polyester, respectively, and
- Mw(2) and Mn(2) represent a weight average molecular weight and a number average molecular weight of the second polymer compound, respectively.

A method for producing a resin mold, the method comprising:
- kneading a resin composition under a condition that a temperature of the resin composition is kept at about 220° C. or lower, the resin composition comprising an aliphatic polyester, a second polymer compound other than said aliphatic polyester, and an organic phosphoric acid compound having a phosphorus content of about 20% by mass or more;
- and
- molding the kneaded resin composition to obtain the resin mold;
- wherein
- the aliphatic polyester and the second polymer compound in the resin mold have a molecular weight distribution satisfying a condition represented by a following equation (1):
- Mw(1)/Mn(1)≧Mw(2)/Mn(2) (1)
- wherein
- Mw(1) and Mn(1) represent a weight average molecular weight and a number average molecular weight of the aliphatic polyester, respectively, and
- Mw(2) and Mn(2) represent a weight average molecular weight and a number average molecular weight of the second polymer compound, respectively.
