Abstract

A resin composition includes at least a cellulose ester resin, a non-reactive plasticizer that does not have a functional group reactable with the cellulose ester resin, and a polyolefin-containing polyfunctional elastomer that includes polyolefin obtained by polymerizing olefins having 2 to 4 carbon atoms as a main component and that has a plurality of functional groups reactable with the cellulose ester resin.

First claim

What is claimed is:

1. A resin composition comprising: at least
a cellulose ester resin;
a non-reactive plasticizer that does not have a functional group reactable with the cellulose ester resin; and
a polyolefin-containing polyfunctional elastomer that includes polyolefin obtained by polymerizing olefins having 2 to 4 carbon atoms as a main component and that has a plurality of functional groups reactable with the cellulose ester resin;
wherein:
the non-reactive plasticizer is at least one selected from a polyether ester compound and a compound containing adipic acid ester;
the polyether ester compound is a compound represented by Formula (2):

wherein each of R 4 and R 5 independently represents an alkylene group having 2 to 10 carbon atoms; each of A 1 and A 2 independently represents an alkyl group having 1 to 6 carbon atoms, an aryl group having 6 to 12 carbon atoms, or an aralkyl group having 7 to 18 carbon atoms; and m represents an integer of 1 or greater; and
the compound containing the adipic acid ester is a compound represented by Formula (2-1) or Formula (2-2):

wherein each of R 4 and R 5 independently represents an alkyl group or a polvoxyalkyl group [—(C x H 2x —O) y —R A1 ]; R A1 represents an alkyl group; x represents an integer of 1 to 6; y is an integer of 1 to 6: R 6 represents an alkylene group; m1 represents an integer of 1 to 5 and m2 represents an integer of 1 to 10.

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

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

3. The resin composition according to claim 1 , wherein the polyolefin-containing polyfunctional elastomer includes at least one selected from an epoxy group and a glycidyl group as a functional group.

4. The resin composition according to claim 2 , wherein the polyolefin-containing polyfunctional elastomer includes at least one selected from an epoxy group and a glycidyl group as a functional group.

5. The resin composition according to claim 1 , wherein a content of the non-reactive plasticizer is 1 part by weight to 40 parts by weight with respect to 100 parts by weight of the cellulose ester resin.

6. The resin composition according to claim 1 , wherein a content of the polyolefin-containing polyfunctional elastomer is 0.5 parts by weight to 20 parts by weight with respect to 100 parts by weight of the cellulose ester resin.

7. A resin molded article comprising the resin composition according to claim 1 .

8. A resin molded article comprising the resin composition according to claim 2 .

9. The resin composition according to claim 2 , wherein:
each of R 1 , R 2 , and R 3 respectively represents a hydrogen atom or an acetyl group; and
a substitution degree of the cellulose ester resin is 2.1 to 2.6.
