PROCESS FOR THE PREPARATION OF ABS RESINS |
摘要 |
Process for the preparation of ABS which comprises: a) preparing a solution consisting of a diblock linear rubber of the type S-B dissolved in a mixture of monomers comprising styrene and acrylonitrile; b) feeding to the solution of step (a) at least one preformed ABS resin having an average volumetric diameter of the rubber particles contained in the polymeric matrix of more than 1.5 .mu.; c) dissolving the preformed ABS in the solution of step (a); d) feeding in continuous the solution thus obtained to a polymerization reactor for ABS resins; e) polymerizing the final solution to produce an ABS with a multimodal morphology.
