摘要： Disclosed are nitrile-vinylidene substituted aromatic polymers which include less than about 250 ppm of vinylidene substituted aromatic monomer. Also disclosed is a method of minimizing nitrile migration in nitrile-vinylidene substituted aromatic polymers where the amount of residual vinylidene substituted aromatic monomer in the nitrile-vinylidene substituted aromatic polymer is reduced. Also disclosed is a method of making nitrile- vinylidene substituted aromatic polymers which includes less than about 250 ppm of styrene monomer.
