Agglomerating agent latex with bound poly(ethylene oxide)

Abstract

A process that is provided for agglomerating rubber particles of a rubbery latex. The process involves producing an agglomerating agent which is in the form of latex having particles which comprise high molecular weight polyoxyethylene bound therein. The agglomerating agent is affixed with an elastomeric latex to form agglomerated elastomeric particles. The process results in the formation of uniform size agglomerating particles, and utilizes a non-surfactant form of polyoxyethylene, which can be utilized in small amounts to yield the desired agglomerated elastomeric latex. The agglomerated particles may then be utilized as the substrate for graft copolymers, such as acrylonitrile-butadiene-styrene graft copolymers.
