Novel block copolymers including acrylonitrile sequences and glutarimide units and processes for preparing same

摘要

There is disclosed block copolymers having acrylonitrile sequences and sequences of glutarimide units of a molecular weight of form about 10,000 to about 2,000,000 where the acrylonitrile sequences and sequences including glutarimide units are of a molecular weight of at least about 400 with the number of sequences being at least about 2 and preferably 5 and higher.
