PROBLEM TO BE SOLVED: To provide a copolymer showing excellent heat resistance by using a polymerizable monomer which gives heat resistance in a further small used amount.SOLUTION: A copolymer is obtained by copolymerizing a monomer represented by formula (1) with another monomer; Rand Rare preferably 1-20C hydrocarbon group, more preferably methyl; and another monomer is preferably a (meth)acrylate. |
