Abstract: A process for applying a polymer additive material to a polymeric substrate includes the steps of a) forming in a closed pressurized system a mixture of a solid polymer additive material, a suitable liquid carrier material, and a suitable viscosity reducing material, and b) spraying this mixture onto a polymeric substrate.

Abstract: A purging composition is provided which is useful for cleaning thermoplastic processing equipment. The composition is composed of the following components in the following concentrations:______________________________________ Component Percent by Weight ______________________________________ Adsorbate 0.05 to 5 Matrix resin 49.5 to 99.5 Abrasive (optional) 0 to 50 ______________________________________The composition can also contain a carrier resin having a melting point different from that of the matrix resin.

Abstract: The present invention discloses an improved method for forming stable dispersions of particulate matter. In particular, the present invention relates to a method of forming stable dispersions of particulate matter in both organic and silicone-based fluids.

Abstract: Antifreeze composition and composition concentrates are disclosed which comprise an alcohol, such as, for example ethylene glycol, a surface modifier, such as, for example, an organophosphate which adheres to the interior surfaces of a cooling system, and a pseudo oil, such as, for example a polypropylene glycol, which forms a film on the surface-modified, interior surfaces of the cooling system. Also disclosed are methods of making and using the composition and composition concentrates.

Abstract: Topical, particularly light selective, compositions and methods using evaporative solvent, and a 0.5:1 to 20:1 ratio of film-forming polymer to topically active agent provide a microdispersion of agent in a polymer film exhibiting enhanced topical activity.

Abstract: A process for enhancing the fabrication of thermoplastic polymers entailing the addition of from 0.01 to 1 part, per hundred parts of thermoplastic polymer, of a processing aid, said processing aid comprising a processing additive, such as a silicon or a polyol, and a processing adjuvant, such as a phosphate.

Abstract: Combinations of glycosaminoglycan and certain cationic polymers provide modified glycosaminoglycan properties and can provide substantivity to keratinous material, compatibility, stability, humectancy, rheology and other properties useful in personal care or medical applications.

Abstract: A coating is applied to a microporous support in the presence of a volatile liquid capable of drawing the coating into the support and of desolvating the coating. The liquid is thereafter volatilized with the resulting dry ultrafiltration membrane being essentially crack-free and having desirable mechanical and chemical stability. The support may be pretreated with a volatile liquid, such as acetone, prior to the applying of the coating to the support. Alternately, the coating material can be dispersed in a volatile liquid, such as methanol, to form a coating suspension that is applied to the support. The coating material, preferably zirconia, will have a particle size within the range of from about 5 m.mu. to about 10.mu., with the coating having a thickness of up to about 20.mu.. The support, such as a porous carbon tube, will have a pore volume of about 5-60% and a pore size of about 5 m.mu.-40.mu.. Stability is enhanced by firing the membrane at 25.degree. C.-1500.degree. C. preferably at about 400.
