Title:
PROCESS FOR PRODUCING RESIN PARTICULATE
Document Type and Number:
WIPO Patent Application WO/2007/125597
Kind Code:
A1
Abstract:
A process for producing resin particulates, in which resin particulates are recovered from an aqueous solution containing resin particulates. In particular, it is intended to provide a process for stably producing resin particulates of an isobutylene polymer, especially an isobutylene block copolymer, excelling in transparency and in blocking property. Such a process can be provided by pulverizing a polymer and thereafter adding a colloidal silica of 0.1 to 0.3 μm particle diameter to an aqueous solution containing the resultant resin particulates.
