摘要
This invention, the majority or without completely using halogen content chemical compound, the heat resistance which is superior, offers building a bridge ones, and the said copolymer of the poly- ether copolymer which it can use as the rubber which oil resistance, resistance fuel oiliness and each low temperature quality is possessed. The constitution unit 60 - 99.8 mols which are displayed with below-mentioned general formula (i) %, the constitution unit 0 - 39.8 mols which are displayed with below-mentioned general formula (ii) %, and the constitution unit 0.2 - 10 mols of building a bridge characteristic oxy run monomer origin % the poly- ether pluralistic copolymer which it possesses. In formula, as for R1 carbon count the alkyl group of 1 - 6, as for R2 the hydrogen atom, carbon count the alkyl group of 1 - 6, as for phenyl group or ch2o r3 and R3 carbon count alkyl group or phenyl group 1 - 6 is meant. Conversion 1
