  • Microcapsule Dispersions
    Publication number: 20080103265
    Abstract: The present invention relates to microcapsule dispersions comprising microcapsules in a hydrophobic solvent, wherein the microcapsules have a capsule core, comprising a water-soluble organic substance, and a capsule shell which is composed essentially of reaction products of polyisocyanates with polyfunctional amines, and also to a process for preparing them and additionally to microcapsules obtainable from the corresponding microcapsule dispersions.

  • Method for agglomerating dispersed rubber
    Patent number: 6812283
    Abstract: A process for the agglomeration of at least one rubber (A), dispersed in an aqueous phase, by the addition of a dispersion of at least one agglomerating polymer (B) in aqueous phase, in which the agglomerating polymer B used is one containing substantially no free acid groups and the agglomeration is carried out in the presence of at least one basic electrolyte.
