Abstract: An improved process for making a mild, detergent-soap, toilet bar containing a C6-C18 acyl isethionate as the principal surfactant in combination with minor proportions of C12-C20 fatty acids, a water soluble soap and water which comprises the step of forming a liquid mixture of said acyl isethionate, fatty acids and soap at a temperature of about 85.degree. C. to 105.degree. C. in the presence of about 0.5% to 2.5% by weight, based upon the bar, of vegetable oil prior to processing said liquid mixture on a chill roll to form particles which are further processed to yield said bar, said liquid mixture having reduced viscosity and being readily pumpable as compared to a liquid mixture prepared in the absence of said vegetable oil. The bar produced by the foregoing process also is part of the invention.

Abstract: Thermoplastic articles molded from amorphous polyamide and polycarbonate resin blends exhibit improved color when irradiated with ionizing radiation.
Abstract: Acid contaminants leached from acidic ion-exchange resins and carried in process streams with phenol are separated from the phenol by passing the process stream in contact with an anionic exchange resin, whereby the acid contaminants react with and bond to the anionic exchange resin.
Abstract: Novel compositions with high impact strength in both thin and thick-walled sections, and good weld line strength at room temperatures are provided in the form of resinous mixtures comprising:(A) an aromatic carbonate polymer resin selected from the group consisting of(i) an aromatic polycarbonate resin,(ii) a poly(ester-carbonate) copolymer resin, and(iii) a mixture of (i) and (ii); and(B) an impact modifier combination therefor comprising(i) a polyester resin selected from the group consisting of(a) a poly(alkyene terephthalate) resin, when (A) is (i) or (iii); and(b) an amorphous copolyester copolymer resin, and(c) a mixture of (a) and (b); and(ii) a diene based, grafted core-shell copolymer.
Abstract: A bottle feeder comprises a tamper evident overcap, which captures a nipple and hold-down cap and has a pop-up indicator to insure the integrity of the bottle is discribed. Upon removal of the overcap the tamper evident band remains on the bottle and the pop-up indicator indicates the feeder has been opened. The nipple and hold-down cap can be withdrawn from the overcap and placed on the bottle for use.
Abstract: Fluoropolymers in the form of solid particles of specified diameter and dispersed in water are added and mixed with polycarbonate resin particles at a rate of 0.1 to 9 liter/hour to obtain a uniform coating of the fluoropolymer on the polycarbonate resin particles. The proportion of fluoropolymer added is from 0.01 to about 70 parts for each 100 parts by weight of polycarbonates and mixing is carried out to continually bring polycarbonate resin particles (non-contacted) into contact with the fluoropolymer dispension as it is added.
Abstract: A process comprising the addition of a degradation inhibiting effective amount of an ammonium, alkali metal, alkaline earth metal or transition metal of oxidation number +2 salt of an aliphatic mono or dicarboxylic acid to a composition comprising a phenol and a bisphenol, the addition occurring prior to a procedure which subjects the bisphenol to substantial heat, said bisphenol produced from an acidic ion exchange resin catalyzed reaction of a phenol and a ketone or aldehyde.
Abstract: Silane esters are transesterified with hydroxyl-terminated polyester resins to obtain end-capped, extended or branched polyester molding compositions.
