| titleOfInvention | Process for the preparation of nitrile group containing polymers |
| abstract | An improved process is disclosed for the preparation of nitrile group containing polymers which comprises reacting a nitrile group containing vinyl monomer with an initiator of the general formula [ArCR 1 R 2 ]⊖[N(R 3 R 4 R 5 R 6 )]⊕ wherein Ar=phenyl, substituted phenyl or a heterocyclic compound, R 1 =R 2 =H, ester, cyano, alkyl, aryl, 1,3-oxazoline, N,N-dimethyl amide and other similar alpha activating groups, or combination of them, or one of R 1 or R 2 together with Ar, where Ar is phenyl or substituted phenyl, is a nitrogen atom containing heterocyclic compound and the other being a nitrile group, R 3 , R 4 , R 5 and R 6 may be same or different and represent substituted alkyl, cycloalkyl, arylalkyl or aryl or two of the R 3 , R 4 , R 5 and R 6 together with nitrogen atom form a heterocycle with the condition that the sum of all carbon atoms or all R 3 , R 4 , R 5 and R 6 is from 12 to 50 and no more than one of the R 3 , R 4 , R 5 and R 6 is an aryl derivative in an inert atmosphere at a temperature not exceeding 60° C. Polymers with molecular weights in the range of 500 to 25,000 can be prepared. Of these polyacrylonitrile, polymethacrylonitrile and the like are known to be very useful and have diverse commercial applications. |
