✦ Synopsis

Radical copolymerizations of zinc dimethacrylate and 2-(N-ethylper¯uorooctanesulphonamido)ethyl acrylate initiated with di-t-butyl peroxy di-isopropylbenzene were carried out in various amounts of DMF for 10 h at 140 °C in the presence of hydrogenated nitrile-butadiene rubber (HNBR) as a simulation of copolymerization without solvent. It was revealed that the M W of the copolymer is about 100000 and that less than 25 mol% of the comonomer is grafted on HNBR. The molar ratio of monomer involved in copolymerization from crosslinking was 0.23. The material produced by in situ copolymerization can be expected to be changed from a polymer alloy or a blend to a graft polymer depending on the double bond content in the HNBR.
