Claim 12:
13. An ultraviolet-protective film formed from a mixture comprising:
a fluorinated copolymer formed from a fluorine-containing monomer and vinyl chloride, the fluorine-containing monomer in an amount of from about 0.5 weight % to about 4.0 weight % based on a combined 100 weight % of the fluorine-containing monomer and vinyl chloride;
a plasticizer; and
a heat stabilizer;
wherein the fluorine-containing monomer is a compound of formula (I), (II), (III), (IV), or (V):, wherein R1 is selected from the group consisting of hydrogen, C1-C18alky, fluorine-containing C1-C18alkyl, C2-C18alkyl comprising —CO2— in either direction between two carbons, and fluorine-containing C2-C18alkyl comprising —CO2— in either direction between two carbons;
m is an integer from 0 to 4;
L is a group selected from the group consisting of fluorine-containing C1-C18alkylene and fluorine-containing aryl(C1-C18)alkylarylene;
n is an integer from 0 to 4;
R2 is selected from the group consisting of fluorine,, R3 is selected from the group consisting of hydrogen and CO2H;
R4 is selected from the group consisting of hydrogen, C1-C18alkyl, and fluorine-containing C1-C18alkyl;
R5 is selected from the group consisting of C1-C18alkyl, fluorine-containing C1-C18alkyl, phenyl, fluorine-containing phenyl, benzyl, fluorine-containing benzyl, benzyl substituted with fluorine-containing C1-C18alkyl, C1-C18alkylbenzyl, and fluorine-containing C1-C18alkylbenzyl;
R6 is selected form the group consisting of hydrogen and fluorine-containing C1-C18alkyl;
provided that R4 and/or R5 and/or R6 comprises fluorine;
each of R7 and R8 is independently selected from the group consisting of fluorine-containing C1-C18alkyl;
each of from one to five R9 groups is independently selected from the group consisting of fluorine, fluorine-containing C1-C18alkyl, and fluorine-containing C2-C18alkyl comprising —O—, or —CO2— in either direction, between two carbons;
R10 is selected from the group consisting of C1-C18alkyl, fluorine-containing C1-C18alkyl, and C2-C18alkenyl; and
R11 is selected from the group consisting of hydrogen, C1-C18alkyl, and fluorine-containing C1-C18alkyl;
provided that R11 is fluorine-containing C1-C18alkyl if R10 is C1-C18alkyl or C2-C18alkenyl.
