Mono(1,3-oxazolin-2-yl)-terminated atactic oligopropene with M(n)=710g/mol was derived in high yields from monoester-terminated oligopropene via reaction with 2-aminoethanol and subsequent Ti(OC4H9)(4)-catalyzed dehydration at 180 degrees C. Cationic bulk polymerization of this novel macromonomer, initiated with 2 mol% methyl-4-nitrobenzenesulfonate at 200 degrees C, afforded high molecular weight poly[N-oligopropene-1-carbonyl-ethyleneimine]. Grafting of mono(1,3-oxazolin-2-yl)-terminated oligopropene with poly(ethene-co-methacrylic acid), containing 3 mol% methacrylic acid, by heating both components for 15minutes at 220 degrees C yielded novel ethene copolymers containing 41wt% ester-amide-coupled oligopropene as side chains.
