摘要

The invention relates to a method to reduce or prevent agglomeration of rubber particles in aqueous media by LCST compounds and elastomers obtained thereby. The invention further relates to elastomer products comprising the same or derived therefrom.

主权项

1. A process for the preparation of an aqueous slurry comprising a plurality of elastomer particles suspended therein, the process comprising:
A) contacting an organic medium comprising
i) at least one elastomer, andii) an organic diluentwith an aqueous medium comprising at least one LCST compound having a cloud point of 0 to 100° C. and B) removing at least partially the organic diluent to obtain an aqueous slurry comprising elastomer particles.
