NOVELTY - A (meth)acrylate homopolymer (I) or (II), is new. USE - New (meth)acrylate homopolymer used for forming fluoroalkyl(meth)acrylate copolymer used as electroconductive improvement agent in composition as matrix for producing electroconductive material (all claimed). ADVANTAGE - The composition has excellent electroconductivity. DETAILED DESCRIPTION - A (meth)acrylate homopolymer of formula (I) or (II), is new. R1,R3 = H or methyl; R2 = alkyl substituted with one to substitutable number of fluoro;and R4 = H, or alkyl, cycloalkyl, non-aryl heterocycloalkyl, aryl, or heteroaryl (all optionally substituted) and excluding fluoroalkyl. INDEPENDENT CLAIMS are included for the following: (1) a composition, which comprises an electroconductive component comprising a fluoroalkyl(meth)acrylate copolymer comprising homopolymer (I) or (II), and a (meth)acryl monomer, or an electroconductive material; (2) the electroconductive material, which comprises the copolymer and electroconductive component of fluoroalkyl(meth)acrylate; (3) manufacture the electroconductive material, which involves obtaining a copolymer by polymerizing the fluoroalkyl(meth)acrylate and a polymerizable monomer, mixing copolymer and electroconductive component, obtaining a mixture, and heating the mixture; and (4) a mixture (m1), which comprises the copolymer comprising the homopolymer (I) or (II), a metal component, and electroconductive carbon based component.
