PROCESS FOR BULK POLYMERIZATION OF ACRYLONITROLE
Acrylonitrile(I), alone or with a comonomer, was polymd. with high conversion by free-radical initiated bulk polymn. under controlled conditions and high reaction medium fluidity. Thus, cumenehydroperoxide, Me2SO3 and Mg(OMe)2 in MeOH were added to I contg. H2O at 50 C. After 30min the polymn. suspe...

| Zusammenfassung: | Acrylonitrile(I), alone or with a comonomer, was polymd. with high conversion by free-radical initiated bulk polymn. under controlled conditions and high reaction medium fluidity. Thus, cumenehydroperoxide, Me2SO3 and Mg(OMe)2 in MeOH were added to I contg. H2O at 50 C. After 30min the polymn. suspension was discharged through an overflow tube. The polyacrylonitrile was continuously filtered, washed and dried 24hr at 60 C. Monomer conversion was 26%. |
