Abstract: Microcapsules having density controlled to be close to that of an aqueous solution are provided which may be dispersed in liquid bleaching solutions and which are useful as coloring or whitening agents.

Abstract: Polymer compositions are provided which may be cast as thin, self-supporting films, useful in forming sealed envelopes or pouches containing granulated pulverulent or non-aqueous liquid materials. The cast films comprise a polymeric matrix, having at least about 50 weight percent polyvinyl alcohol, and a plurality of microdomains dispersed throughout the polymeric matrix. The films have good resistance to breakage at low temperatures and low relative humidities.

Abstract: Precrosslinked nitrile rubber polymers are prepared by interpolymerizing a polyol polyacrylate with butadiene and acrylonitrile to improve compression set, extrusion rate and die swell properties of the precrosslinked polymers and blends thereof with linear nitrile rubber polymers without sacrificing other physical and processing properties.

Abstract: This invention relates to a process of producing elastomeric particles, such as those of natural and synthetic powdered and crumb rubbers and to the compositions prepared in accordance with such process. Specifically, the invention comprises encapsulating the elastomeric particles with a coating or film of a preplasticized vinyl resin, such as, for example, polymers and copolymers of vinyl and vinylidene halides and the like. The resultant composite particles are free-flowing and free of irreversible agglomeration and can be used in dry-blending with other materials prior to being formed into useful articles.
