Abstract: This invention is concerned with certain vinyl resin coating compositions in which the vinyl resin binder or film-forming component is normally dissolved in an organic solvent which is volatilized after application of the composition to the surface of substrates to be finished. The vinyl resin component is generally of high molecular weight and it is normally difficult to obtain a reasonable viscosity in the coating composition without excessive dilution with organic solvent and the necessity to apply a plurality of coats to obtain the desired protective thickness. The present invention has been found to alleviate or reduce this difficulty in the particular solution coating compositions with which it is concerned, namely thermoplastic vinyl or acrylic polymer solutions, polyvinyl acetals, and chlorinated polyisoprene containing about 64-65% chlorine.

Abstract: The present invention is concerned with novel monomers containing sulfonic acid groups or salts thereof and polymers thereof which are useful for many purposes, such as antistatic agents for textiles and other shaped articles formed of hydrophilic materials. They are useful for making copolymers that are particularly valuable in coating compositions, especially in the form of aqueous latices or organic solvent solutions thereof. Examples of the monomers are of the formula ##STR1## wherein R is hydrogen or lower (C.sub.1 -C.sub.4)alkyl, such as methyl,A is an alkylene group having 2 to 10 carbon atoms, at least 2 of which extend in one chain between the oxygen atoms, andX is an aromatic nucleus or an alkyl group, substituted by a sulfonic acid group and optionally one or more groups selected from sulfonic acid, carboxylic acid, and lower alkyl, such as methyl, ethyl, propyl, or butyl.

Abstract: The present invention is concerned with film-forming polymer dispersions, especially in aqueous systems, such as aqueous solutions of polymers of monoethylenically unsaturated monomers as well as latices or dispersions in an aqueous medium of water-insoluble particles of polymers, such as those obtained by emulsion polymerization. It involves the addition to such aqueous polymer systems in order to improve hardness, blocking-resistance and film-formation at room temperature or below, of a non-volatile, reactive monomer comprising dicyclopentenyl acrylacte or methacrylate to serve as an air-curing coalescent.

Abstract: Novel, versatile aminolysis products are obtained by aminolyzing, with a polyamine of aliphatic nature, an oligomeric homopolymer of an alkyl methacrylate in which the alkyl group contains from 1 to 6 carbon atoms or an oligomeric copolymer of at least two alkyl methacrylates, such oligomers being produced from monomeric alkyl methacrylates by anionic polymerization to provide number average molecular weights in the range of 600 to 10,000 and preferably in the range of 1,000 to 5,000. Alternatively, an anionically polymerized homo-oligomer of a (C.sub.1 -C.sub.6)-alkyl acrylate or co-oligomer of at least two alkyl acrylates in which the alkyl in at least one monomer has from 1 to 6 carbon atoms in the co-oligomer, and the alkyl in the comonomers may have from 1 to 18 or more carbon atoms, are aminolyzed with a polyamine of aliphatic nature.

Abstract: The invention is concerned with novel unsaturated compounds having extremely low volatility having a single monoethylenically unsaturated group of the formula H.sub.2 C = C < whereby they are capable of polymerization to produce linear homopolymers and copolymers with copolymerizable monomers containing such a group, and having autoxidizable characteristics by virtue of a different type of unsaturated group. These new compounds are useful for the production of polymers, alone or in admixture with other polymers or monomers to modify the characteristics of the components of the mixture. They are useful in coating or impregnating compositions and/or in the molding, casting, or otherwise forming of shaped articles.

Abstract: This invention is concerned with coating compositions comprising an unsaturated polyol/polycarboxylic acid alkyd or polyester condensate resin (including drying oil-modified alkyd), the polycarboxylic acid or anhydride precursor(s) of which alkyd may be aromatic, aliphatic, or both. In one preferred embodiment Type A, the polyacid is predominantly or exclusively aliphatic and in another Type B, it is predominantly or exclusively aromatic in character. The alkyd or polyester is carried (dissolved) predominantly or exclusively in a substantially non-volatile reactive liquid consisting essentially of a) dicyclopentenyl acrylate or methacrylate or mixtures thereof or of b) a mixture of such (meth)acrylate with one or more alkyl or alkenyl esters of acrylic or methacrylic acid in which the alkyl and/or alkenyl group contains 10 to 20 carbon atoms.

Abstract: N,N'-bis(trialkylamino)alkanediimides are useful as intermediates for forming latent isocyanates which in turn are useful for curing polymers containing active hydrogen, and as reactants in the production of polyurethane resins. The difunctional N,N'-bis(trialkylamino)alkanediimides are prepared by reacting a dicarboxylic acid dihydrazide with an alkyl halide to quaternize the dihydrazide and then neutralizing the resulting salt with an appropriate base in either aqueous or alcohol medium.

Abstract: Novel acyl-containing amine hydrochlorides are produced by first converting the amino group or groups of an amino acid to an acid salt by reaction with hydrochloric acid and the resulting product is reacted with an alkanolamine or diol in an inert liquid medium while passing a stream of hydrogen chloride gas therethrough. The amine hydrochlorides produced in this manner may be converted to the corresponding isocyanates by reaction with phosgene or other carbonyl dihalide.
