Process for preparing copolymers of vinyl-aromatic monomers with ethylenically unsaturated nitriles having low content of unreacted residual monomers |
摘要 |
Process for preparing copolymers of vinyl-aromatic monomers with ethylenically unsaturated nitriles having a very low content of unreacted residual monomers, consisting in adding to the polymerization dispersion, containing a compound capable of giving free radicals, and in the final step of the polymerization process, from 0.2 to 2% by weight of a comonomer which is reactive towards the unreacted monomers.
