This invention relates to abrasive compositions useful in preparing purge compositions for purging plastics processing equipment comprising: (A-1) at least one abrasive powder comprising a major amount of calcium carbonate; (A-2) at least one organic rosin material; and (A-3) at least one surfactant. The abrasive compositions of the present invention further may comprise at least one viscosity reducing organic diluent. The purging compositions of the present invention comprise (A) a minor amount of the abrasive composition of the invention, and (B) a major amount of at least one polymer or resin. These purging compositions allow fast and effective purging of processing equipment. These compositions may also be reused, i. e. , used for more than one purging operation, and they may be recycled by incorporating the used purge composition into a polymer which is identical to or compatible with the polymer (B) of the purge composition. The invention also relates to a method of purging plastics processing equipment utilizing the purging compositions described herein.

This invention relates to an abrasive composition comprising (a) a major amount of at least one abrasive powder, (b) at least one resin selected from the group consisting of a polymer of a diene, a rosin material, a coumarone-indene resin, and a mixture of two or more thereof, and (c) at least one copolymer of an olefin and an acrylate or a methacrylate. The abrasive composition may additionally include (d) a surface active agent. The abrasive composition may be added to a polymer or resin to form purge compositions. The invention also relates to methods of cleaning processing equipment and preparing the abrasive compositions and purge composition.

The present invention provides a light reflecting polymeric composition that includes at least one halogenated-flame-retardant-additive-free polymer having dispersed therein a pigment package including a combination of SbOand TiO. The SbOand TiOpreferably have an average particle size within the range of from about 0. 05 μm to about 1. 0 μm, and more preferably about 0. 2 μm. When used in combination, the SbOand TiOpigments synergistically interact together to provide a polymeric composition exhibiting a reflectivity that is substantially higher than can be obtained by the use of either of the pigments alone.
