Abstract
A copolymer comprising an alkyl acrylate and an unsaturated ester compound represented by the following general formula: EQU CH.sub.2 .dbd.CRCOO(CH.sub.2)nPhOR', (1) EQU CH.sub.2 .dbd.CRCOO(CH.sub.2)nOCO(CH.sub.2)mPhOR', (2) EQU CH.sub.2 .dbd.CHOCO(CH.sub.2)nOCO(CH.sub.2)mPhOR', (3) EQU CH.sub.2 .dbd.CHO(CH.sub.2)nOCO(CH.sub.2)mPhOR' or (4) EQU CH.sub.2 .dbd.CHPh(CH.sub.2)nOCO(CH.sub.2)mPhOR' (5) where R is a hydrogen atom or a methyl group; R' is a hydrogen atom, an acyl group or a trialkylsilyl group; and Ph is a phenylene group, forms a blend rubber having a good heat resistance and a good amine resistance with a fluorine-containing elastomer.
