Vinylidene fluoride resin-based shaped product
First Claim
1. A vinylidene fluoride resin-based shaped product of a composition comprising 100 parts by weight of a vinylidene fluoride resin and from 1 to 200 parts by weight of a copolymer comprising a monomer (A) having the formula:
- ##STR7## wherein R1 is H or CH3, and X1 and X2 are each a saturated hydrocarbon group containing from 1 to 4 carbon atoms, H or halogen and a monomer (B) having the formula;
##STR8## wherein R2 is H or CH3 and R3 is a saturated hydrocarbon group containing from 1 to 5 carbon atoms, the molar ratio of the monomer (A) to the monomer (B) being not more than 1, and the monomer (A) which is a constituent unit of said copolymer being present in a quantity of at least 1×
10-4 moles per square meter of light-receiving area of said shaped product.

Abstract
A vinylidene fluoride resin composition is obtained by mixing into a vinylidene fluoride resin a copolymer of a monomer (A) having the formula: ##STR1## wherein R1 is H or CH3, and X1 and X2 are each a saturated hydrocarbon group containing from 1 to 4 carbon atoms, H or halogen, and a monomer (B) having the formula: ##STR2## wherein R2 is H or CH3 and R3 is a saturated hydrocarbon group containing from 1 to 5 carbon atoms. Shaped products, particularly films obtained from this composition exhibit excellent ultraviolet shielding off effect and excellent transparency.
