摘要:
The invention is a processing aid for thermoplastic polyesters which is a salt of a polycarboxylic acid or the salt of a polycarboxylic partial ester. The polycarboxylic acids are partial esters or sales of modified acids such as succinic acid, adipic acid, phthalic acid, citric acid, dicarboxylphenyl group and the like. The addition of the processing aid improves the slip and transparency.

Compositions containing esters based on linear fatty acids, esters based on branched fatty acids, esters based on fatty acids containing alicyclic structural elements and esters based on fatty acids containing aromatic structural elements are suitable as solvents for printing inks.
摘要:
The invention relates to a process for producing a polymer or copolymer from monomer material comprising an acrylate, methacrylate, or mixture of such monomers, which comprises the steps of: (a) charging into a continuous tube reactor a feedstock comprising said monomer material and a polymerization initiator; (b) maintaining a flow rate of said material through the reactor at a reaction temperature in the reactor and under pressure sufficient to provide a residence time of the feedstock in the reactor during which polymerization will occur, to form a resin product in the reactor, and said resulting resin product comprising unreacted monomer, and (c) devolatilizing said resin product exiting the reactor to remove unreacted monomers, to provide a substantially monomer-free resin product. Further, the invention relates to resin product made by the process. In particular, the invention relates to resin that has a weight average molecular weight of 10,000 or less, and a glass transition temperature of less than 0° C., preferably −20° C. or lower. The resin product of the invention is particularly useful as an additive for coating and casting resin systems.
摘要:
A process for controlling foam in a water-based electrophoretic coating bath for coating an electrically conductive substrate wherein the bath contains at least one cathodically depositable synthetic resin by adding to the bath a polyalkylene oxide compound whose oxyalkyl groups contain 2 to 4 carbon atoms and the terminal OH groups are esterified with a carboxylic acid or etherified with an allyl or methyl aryl group and has a solubility of more than 50 parts by weight in 100 parts by weight of water at 25.degree. C.

摘要:
The use of fatty oil ex Helianthus annuus containing 78 to 92% by weight oleic acid and 2 to 10% by weight linoleic acid for the production of alkali metal, ammonium and/or alkanolammonium salts of optionally dihydroxy-substituted fatty acids as emulsifiers for emulsion polymerization. Excellent polymerization results are obtained despite the high linoleic acid content.
