Abstract: Recompoundable polyvinyl chloride suitable for reuse, for example, in cable and wire production is recovered from a scrap material which includes plasticized polyvinyl chloride. A charge of plasticized polyvinyl chloride scrap material is treated with a solvent to form a solvent mixture with one component thereof being a solvent solution of dissolved vinyl chloride polymer and plasticizers. The mixture is heated and agitated and scrap metal and other gross solids, if present, are removed. Then the solvent mixture is treated with an acid which advantageously causes a flocculation of suspended insolubles such as pigments and fillers. Except when using cyclohexanone as the solvent, the treatment with the acid must be accomplished, unexpectedly, in the presence of an additional flocculating agent.

Abstract: A white, bright and opaque urea formaldehyde pigment is prepared in a continuous process by precipitating a urea formaldehyde resin or prepolymer having a relatively low water tolerance and a relatively high viscosity in an aqueous precipitating bath containing an acid catalyst. The reaction is carried out by supplying the urea formaldehyde resin to one or more reactors each containing the precipitating bath at an elevated temperature and under agitation, wherein a precipitate begins to form almost immediately. The reaction is allowed to progress for a length of time sufficient to permit most of the higher molecular weight fractions of the resin to precipitate out, the precipitate is then filtered preferably at the reaction temperature, washed and collected.

Abstract: Rubber compounds are readily bonded to reinforcing elements, particularly tire cords of glass fibers, using a one-step dip process in which the dip contains an alkaline aqueous dispersion of a mixture of a major amount by weight of a rubbery vinyl pyridine/styrene/butadiene terpolymer and a lignin sulfonate-resorcinol-formaldehyde reaction product. Good adhesion of the cords to a rubber compound are obtained with this process.

Abstract: The fire retardancy of polyesters is enhanced with halophenoxyphosphazenes that contain a P--O--P bond. Preferred materials are reaction products of a halogenated phenol and a phosphonitrilic halide. Brominated phenols are preferred although chlorophenols can be used. Of the brominated phenols, preferred starting materials are p-bromophenol, 2,4-dibromophenol and mixtures thereof. Phosphonitrilic chlorides are preferred starting materials. Pure phosphonitrilic halides can be used; however, phosphonitrilic halide mixtures are preferred because of their availability. Cyclic and linear phosphonitrilic halides are useful as well as mixtures thereof. Saturated and unsaturated polyesters can be made fire retardant by this invention, as can thermoplastic and thermosetting materials. Linear and crosslinked polyesters can be treated. Preferred polyesters are fiber-forming polyesters of a diol and dibasic acid, such as poly(ethylene terephthalate) and poly(1,4-cyclohexylenedimethyleneterephthalate).
