Provided are a fluorine-containing (meth)acrylic (co)polymer that scarcely generates gas when subjected to molding process, and is capable of supplying a molded body excellent in external appearance and transparency; a fluorine-containing (meth)acrylic resin film thereof; and a fluororesin laminated resin film having the same properties. The (co)polymer is a fluorine-containing (meth)acrylic (co)polymer obtained by polymerizing a monomer component including 100 to 70% by weight of a fluoroalkyl(meth)acrylate monomer, and 0 to 30% by weight of a different monomer copolymerizable therewith by effect of a radical polymerization initiator having a solubility in water of 0.1% or less by weight at 25 C, and having 8 to 14 carbon atoms.

Fluorine-containing (meth) acrylic (co) polymer and molded body films thereof

An object of the present invention is to provide a foaming vinyl chloride resin composition having excellent foaming properties and providing a foam molded product with an excellent appearance by enhancing the melt strength of the vinyl chloride resin composition. A processability improver for foam molding according to the present invention includes a (meth)acrylic polymer powder with a weight average molecular weight of 2,000,000 to 7,000,000, wherein the (meth)acrylic polymer powder includes 1 to 20% by weight of a (meth)acrylic polymer (A) with a weight average molecular weight of 10,000 to 300,000, and 80 to 99% by weight of a (meth)acrylic polymer (B) with a weight average molecular weight of 2,000,000 to 7,000,000.

Processability improver for foam molding and vinyl chloride resin composition containing same

The present invention provides a (meth)acrylic resin composition, in which thermal degradation when processing is inhibited and discoloring hardly occurs, which could not be obtained in the conventional (meth)acrylic resin composition containing (meth)acrylic resin prepared by suspension polymerization. More specifically, the present invention relates to a (meth)acrylic resin composition comprising 100 parts by weight of a methyl methacrylate polymer obtained by suspension polymerizing 50 to 100% by weight of methyl methacrylate and 50 to 0% by weight of a monomer copolymerizable therewith, 1 to 200 parts by weight of a copolymer having a multi-layer structure and 0.02 to 10 parts by weight of a fatty acid metallic salt.
