摘要:
Water-in-oil emulsions wherein the emulsifier consists essentially of copolymers of N-vinylpyrrolidone and a vinyl C.sub.5-24 alkylcarboxylate (if desired with vinyl acetate) and the continuous phase is a cosmetically acceptable oily material can be prepared easily, safely and inexpensively. The emulsions are substantially odorless and are cosmetically acceptable for the care of the skin.

摘要:
Alkyd resin mixtures for use in stoving water lacquers which contain polyols having an average molecular weight of from 200 to 2000 g/mole, an average --OH functionality of >2, and terminal groups of the formula, --CHR--OH in which R=--H, --CH.sub.3, or both --H and --CH.sub.3.
摘要:
Process for the production of alkyd resins having a final acid number of not more than 40 and a high --OH number for use in water lacquers. The resins of the invention can be made up with the aid of aminoalcohols containing more than two hydroxyl groups into optically clear water lacquers which are distinguished both by their lack of environmental problems and also by their advantageous lacquer properties.
摘要:
This invention is directed to the telomerization of water-soluble monomers in an aqueous phase. More particularly, this invention is directed to a process for the telomerization of water-soluble monomers and water-insoluble telogens in aqueous phase, wherein the water-insoluble telogens are solubilized by the addition of an effectively solubilizing amount of surface-active compounds.
摘要:
A stabilized thermoplastic composition comprised of polyvinyl chloride or mixed polymers containing mainly vinyl chloride units together with stabilizers and other conventional additives employed in thermoplastic compositions, which have as major stabilizer component, a content of 0.02 to 5 parts by weight of aliphatic polyhydroxyl compounds containing 4 to 6 OH-groups per 100 parts by weight of polymer. These polyhydroxyl compounds should contain at least one carboxyl and/or carbonyl group and/or double bond. Suitable compounds are gluconic acid, glucuronic acid, ketogluconic acid, ascorbic acid or the alkali metal salts or alkaline earth salts of the mentioned acids.Other conventional processing additives may be present. The invention concerns also a process for the manufacture of pipes, profiles, foils, hollow parts by hot forming, with the use of the mentioned additives, and the additional use of paraffin, free fatty acid, epoxidized soybean oil or higher molecular weight ester wax.
