C. Worner et al., SYNTHESES OF MONO(1,3-OXAZOLIN-2-YL)-TERMINATED OLIGOPROPENE MACROMONOMERS AND NOVEL POLYMERS CONTAINING OLIGOPROPENE SIDE-CHAINS, Polymer bulletin, 36(3), 1996, pp. 303-309
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)-catalyze
d dehydration at 180 degrees C. Cationic bulk polymerization of this n
ovel macromonomer, initiated with 2 mol% methyl-4-nitrobenzenesulfonat
e at 200 degrees C, afforded high molecular weight poly[N-oligopropene
-1-carbonyl-ethyleneimine]. Grafting of mono(1,3-oxazolin-2-yl)-termin
ated 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-amid
e-coupled oligopropene as side chains.
