摘要:Disclosed are reactive anionic initiators of the general formula [ArCHR 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 a 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 to 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 of 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. The initiators which are in the form of solids or liquids are insoluble and can be incorporated which enable the synthesis of a wide range of polymers with functional groups. These initiators are useful for polymerizing very reactive vinyl monomers such as nitrile bearing vinyl compounds.
