ABSTRACT:
(a) CH.sub.a .dbd.CRCOOR.sub.2 OCOR.sub.1, (b) CH.sub.2 .dbd.CRCOO(CH.sub.2)nPhOR', (2) CH.sub.2 .dbd.CRCOO(CH.sub.2)nOCO(CH.sub.2)mPhOR', (3) CH.sub.2 .dbd.CHOCO(CH.sub.2)mPhOR', (4) CH.sub.2 .dbd.CHOCO(CH.sub.2)nOCO(CH.sub.2)mPhOR', (5) CH.sub.2 .dbd.CHO(CH.sub.2)nOCO(CH.sub.2)mPhOR' or (6) CH.sub.2 .dbd.CHPh(CH.sub.2)nOCO(CH.sub.2)mPhOR' where R is a hydrogen atom or a methyl group, R.sub.1 is an alkyl group, R.sub.2 is an alkylene group, R' is a hydrogen atom, an acyl group or a trialkylsilyl group and Ph is a phenylene group, provides a blend rubber having an improved cold resistance and an intermediate heat resistance between the heat resistance of acrylic copolymer elastomer and that of fluorine-containing elastomer, when blended with the fluorine-containing elastomer.
