Abstract
Provided is a molded body of a resin composition, which has improved easy wiping-off properties and scratch resistance. This resin composition contains (1) a thermoplastic resin and (2) a fluorine-containing copolymer; and the fluorine-containing copolymer (2) is a copolymer which comprises (a) a repeating unit formed from a fluorine-containing monomer represented by formula CH2═C(—X)—C(═O)—Y—Z—Rf, and (b) a repeating unit formed from a non-fluorine monomer having a hydrocarbon group with 14 or more carbon atoms, and which has a weight average molecular weight of 2,500-20,000.
Claims11
A resin composition comprising:
- (1) a thermoplastic resin, and
- (2) a fluorine-containing copolymer,
- wherein the fluorine-containing copolymer (2) is a copolymer which comprises:
- (a) a repeating unit formed from a fluorine-containing monomer represented by the formula:
- CH2═C(—X)—C(═O)—Y—Z—Rf
- wherein X is a hydrogen atom, a monovalent organic group or a halogen atom,
- Y is —O— or —NH—,
- Z is a direct bond or an divalent organic group, and
- Rf is a fluoroalkyl group having 4 to 6 carbon atoms, and
- (b) a repeating unit formed from a fluorine-free monomer containing a hydrocarbon group having at least 14 carbon atoms, and
- which has a weight-average molecular weight of 2,500 to 20,000.
A method of producing a molded body, comprising steps of:
- (i) mixing a thermoplastic resin (1) with a fluorine-containing copolymer (2) to obtain a resin composition;
- and
- (ii) molding the resin composition,
- wherein the fluorine-containing copolymer (2) is a copolymer which comprises:
- (a) a repeating unit formed from a fluorine-containing monomer represented by the formula:
- CH2═C(—X)—C(═O)—Y—Z—Rf
- wherein X is a hydrogen atom, a monovalent organic group or a halogen atom,
- Y is —O— or —NH—,
- Z is a direct bond or an divalent organic group, and
- Rf is a fluoroalkyl group having 4 to 6 carbon atoms, and
- (b) a repeating unit formed from a fluorine-free monomer containing a hydrocarbon group having at least 14 carbon atoms, and
- which has a weight-average molecular weight of 2,500 to 20,000.
