摘要: A continuous process for the manufacture of impact resistant polymers is disclosed. The process comprise polymerization of a reaction mixture containing vinylaromatic monomers in the presence of soluble rubber and entails shearing at least some of said mixture at a rate of more than 30000 1/s using a device having no rotating parts. The resulting product is characterized in its low gloss and improved impact properties.

摘要: A process for the preparation of a blend of ABS polymers is disclosed. The invention comprises introducing a core/shell grafted rubber in the form of powder (crumb) to at least one stage of the continuous mass polymerization process for making an ABS polymer. Accordingly, the process comprises, in sequence, steps (i) through (iii) wherein (i) refers to charging into a first reactor a material system containing primarily monoalkenylaromatic monomer and an ethylenically unsaturated nitrile monomer having dissolved therein diene rubber under conditions to promote at least partial polymerization to form a partially polymerized first mixture and where (ii) refers to polymerizing the first mixture in a subsequent reactor to form a subsequent mixture and where (iii) refers to devolatilizing the subsequent mixture, and introducing said core/shell grafted rubber into at least one of step (i), (ii) and (iii) to yield a blend having a dispersed grafted rubber phase with a bimodal or multimodal particle size distribution.
