Abstract

According to an exemplary embodiment of the present invention, there is provided a resin composition containing a cellulose ester resin, a compound containing an adipic acid ester, and a maleic anhydride-modified ethylene-vinyl acetate copolymer and a resin composition containing a cellulose ester resin, a compound containing an adipic acid ester, and a polyhydroxyalkanoate resin.

First claim

What is claimed is:

1. A resin composition, comprising:
a cellulose ester resin;
a compound containing an adipic acid ester; and
a maleic anhydride-modified ethylene-vinyl acetate copolymer.

2. The resin composition according to claim 1 ,
wherein the cellulose ester resin is represented by formula (1):

wherein R 1 , R 2 and R 3 each independently represent a hydrogen atom or an acyl group having 1 to 3 carbon atoms, and
n represents an integer of 1 or more.

3. The resin composition according to claim 2 ,
wherein the cellulose ester resin represented by formula (1) has an acetyl group as the acyl group each independently represented by R 1 , R 2 and R 3 , and
a substitution degree of acetyl group is 2.1 to 2.6.

4. The resin composition according to claim 1 ,
wherein an amount of the compound containing an adipic acid ester is 5 to 20 parts by mass per 100 parts by mass of the cellulose ester resin.

5. The resin composition according to claim 1 ,
wherein an amount of the maleic anhydride-modified ethylene-vinyl acetate copolymer is 2 to 10 parts by mass per 100 parts by mass of the cellulose ester resin.

6. A resin shaped product comprising the resin composition according to claim 1 .

7. The resin composition according to claim 1 ,
wherein a mass ratio of the cellulose ester resin to the total resin composition is 50% by mass to 95% by mass.

8. The resin composition according to claim 1 ,
wherein a mass ratio of the cellulose ester resin to the total resin composition is 60% by mass to 90% by mass.

9. The resin composition according to claim 1 ,
wherein an amount of the compound containing an adipic acid ester is 9 to 16 parts by mass per 100 parts by mass of the cellulose ester resin, and
an amount of the maleic anhydride-modified ethylene-vinyl acetate copolymer is 2 to 5 parts by mass per 100 parts by mass of the cellulose ester resin.

10. The resin composition according to claim 1 ,
wherein the maleic anhydride-modified ethylene-vinyl acetate copolymer has a density of 0.9 to 0.94 and a melting point of 90° C. to 100° C.
