Abstract

There is provided a resin composition which contains a cellulose ester resin, a polyether ester compound, and an additive if necessary, the resin composition being capable of providing a resin shaped product with excellent transparency, tensile fracture energy property, and the like, and of being suppressed from deterioration of flowability.

First claim

What is claimed is:

1 . A resin composition, comprising:
a cellulose ester resin; a polyether ester compound; and an acrylonitrile-butadiene-styrene copolymer.

2 . The resin composition according to claim 1 ,
wherein a mass ratio of the cellulose ester resin to the acrylonitrile-butadiene-styrene copolymer is 100/8 to 100/2.

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

wherein R1, R2 and R3 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.

4 . The resin composition according to claim 3 ,
wherein the cellulose ester resin represented by formula (1) has an acetyl group as the acyl group each independently represented by R1, R2 and R3, and a substitution degree of acetyl group is 2.1 to 2.6.

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

wherein R4 and R5 each independently represent an alkylene group having 2 to 10 carbon atoms,
A1 and A2 each independently represent an alkyl group having 1 to 6 carbon atoms, an aryl group having 6 to 12 carbon atoms, or aralkyl group having 7 to 18 carbon atoms, and
m represents an integer of 1 or more.

6 . The resin composition according to claim 5 ,
wherein R5 is a n-butylene group.

7 . The resin composition according to claim 5 ,
wherein at least one of A1 and A2 represent an aryl group or an aralkyl group.

8 . The resin composition according to claim 1 ,
wherein a weight average molecular weight (Mw) of the polyether ester compound is 450 to 650.

9 . The resin composition according to claim 1 ,
wherein a mass ratio of the cellulose ester resin to the polyether ester compound is 100/25 to 100/5.

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