Abstract

Provided are a resin additive composition which is excellent in fluidity and can impart excellent physical properties to a thermoplastic resin, a thermoplastic resin composition, and a molded article thereof.A resin additive composition is composed of a phosphoric acid ester compound (A) represented by the following general formula (1):(in the formula (1), R1 to R4 each independently represent a hydrogen atom or a linear or branched alkyl group having 1 to 9 carbon atoms, and R5 represents an alkylidene group having 1 to 4 carbon atoms) and a fatty acid sodium salt (B) represented by the following general formula (2):(in the formula (2), R6 represents a group introduced from an aliphatic organic acid having 7 to 30 carbon atoms), and the mass ratio of (B)/(A) is 0.55 to 2.0.

First claim

The invention claimed is:

1 . A resin additive composition, comprising:
a phosphoric acid ester compound (A) represented by the following general formula (1):

wherein R 1 to R 4 each independently represent a hydrogen atom or a linear or branched alkyl group having 1 to 9 carbon atoms, and R 5 represents an alkylidene group having 1 to 4 carbon atoms; and
a fatty acid sodium salt (B) represented by the following general formula (2):

wherein R 6 represents a group introduced from an aliphatic organic acid having 7 to 30 carbon atoms;
wherein a ratio of an amount of the phosphoric acid ester compound (A) and an amount of the fatty acid sodium salt (B) is in the range of (B)/(A)=0.55 to 2.0 by mass ratio, and
wherein the resin additive composition does not comprise a petroleum resin.

2 . A thermoplastic resin composition, wherein the resin additive composition according to claim 1 is contained in such a manner that the phosphoric ester compound (A) represented by the general formula (1) is 0.001 to 10 parts by mass based on 100 parts by mass of a thermoplastic resin.

3 . The thermoplastic resin composition according to claim 2 , wherein the thermoplastic resin is a polyolefin resin.

4 . The thermoplastic resin composition according to claim 2 , further containing 1 to 80 parts by mass of a thermoplastic elastomer (C) and 1 to 80 parts by mass of a filler (D).

5 . The thermoplastic resin composition according to claim 4 , wherein the thermoplastic elastomer (C) is a copolymer of ethylene and an α-olefin or a copolymer of ethylene and a vinyl ester.

6 . The thermoplastic resin composition according to claim 2 , further containing 0.01 to 10 parts by mass of a phosphite compound (E) represented by the following general formula (3):

wherein R 7 and R 8 each independently represent an alkyl group having 1 to 40 carbon atoms or an aryl group having 6 to 40 carbon atoms.

7 . A molded article characterized by using the thermoplastic resin composition according to claim 2 .
