Abstract: A monosecondary amine containing blocked primary amine groups is provided by reacting a monosecondary amine containing at least one primary amine group (such as diethylene triamine) with a ketone which is hindered to prevent reaction with secondary amino hydrogen atom (such as methyl isobutyl ketone) while removing water. This product disperses in water with the aid of a solubilizing acid to provide a solution which will emulsify a liquid polymer dispersed therein. The water hydrolyzes the blocked primary amine groups to restore reactivity. This product can also be reacted with 1,2-oxirane or isocyanate-functional polymers to provide products which are dispersible in water with a solubilizing acid. These dispersions will electrodeposit at the cathode.

Abstract: Polymeric coatings are provided on steel pipes to protect the same against corrosion. Monomers and prepolymers are permanently adhered to the surface of steel pipes by graft polymerization to form a barrier which keeps out moisture, oxygen and other corrosive gases from the steel substrate. The monomers and prepolymers are chosen to provide a low moisture vapor transmission rate and oxygen permeability.

A process for the preparation of these hydrophilic latex particles, wherein a monomer which is sparingly soluble in water or several monomers which are sparingly soluble in water are dispersed in water and, with the exclusion of oxygen, for example in an inert atmosphere, are homo- or co-polymerized by emulsion polymerization in the presence of a water-soluble, radical-forming initiator but without any addition of an emulsifier, stabilizer or wetting agent.A diagnostic agent containing these hydrophilic latex particles as carrier and biologically and/or immunologically active substances covalently bound to this carrier either directly or via a coupling agent as a bridge.

Abstract: Sized glass fibers are provided that enables the production of sized glass fibers having improved filamentization. When these sized glass fibers are used for reinforcing polymeric materials the reinforced polymeric materials having good mechanical properties such as tensile strength and compaction without fuzz, fly or static properties of the strands. The reinforced polymeric materials and other improvements of the present invention eminate from the use of an interaction product of an epoxidized polar thermoplastic copolymer and an amino organo silane coupling agent in an aqueous sizing composition that also contains a predominant amount of a cross-linkable film former. The aqueous sizing composition has one or more cross-linkable film formers, one or more organo silane coupling agents and about 2 to about 12 weight percent of an interaction product of an unhydrolyzed or partially hydrolyzed amino organo silane coupling agent and an epoxidized polar thermoplastic copolymer.

Abstract: This invention relates to an improvement in a process for producing a latex containing dispersed polymer. The improvement in the process for polymerizing a reaction mixture of vinyl monomer, stabilizer, oxidizing agent and reducing agent comprises using a water-soluble ketone bisulfite as the reducing agent, either alone or with other reducing agents, the ketone having from 3 to 8 carbon atoms in the structure. During the polymerization, the ketone bisulfite is maintained in stoichiometric excess of the oxidizing agent. Vinyl acetate-ethylene copolymers are some of the preferred polymer systems produced.

Abstract: An aqueous sizing composition, method of preparing same and sized glass fibers are provided that enables the production of sized glass fibers having improved filamentization. The aqueous sizing composition has one or more cross-linkable film formers, one or more organo silane coupling agents and about 2 to about 12 weight percent of an interaction product of an unhydrolyzed or partially hydrolyzed amino organo silane coupling agent and an epoxidized polar thermoplastic copolymer. The epoxy copolymer has about 2 to about 12 parts of monomer with epoxy functionality per 100 parts of copolymer. Also the epoxy copolymer has a glass transition temperature (Tg) of from -10.degree. C. to about 70.degree. C. The unhydrolyzed or partially hydrolyzed amino silane coupling agent is contacted with the epoxidized copolymer, where the copolymer has a percent solids in the range of about 15 to about 60 weight percent.

Abstract: Aqueous emulsions and a process for producing aqueous emulsions useful in air drying and stoving paints with improved stability over long periods are described. Fatty acid esters carrying ether-like bound polyethyleneglycol radicals are reacted with conventional alkyd resin raw materials to provide an alkyd resin intermediate which is esterified with an acidic vinyl copolymer carrying methacrylic acid and oil fatty acid radicals. The excellent stability characteristics of the products, despite the relatively low content of polyglycol of from 3 to 8%, is believed due to the substantially unsaponifiable linkage of the stabilizing groups to the resin molecule.

Abstract: Room temperature curable latices can be produced by copolymerizing ketimine derivative ethylenically unsaturated monomers with conventional ethylenically unsaturated monomers in an emulsion process at a controlled pH greater than about 7.2 to produce a coagulum-free latex containing blocked amine (--NH.sub.2) groups. In use, the pH of the latex can be adjusted to acidic below 7 to generate unblocked reactive amino groups which can be cured or cross-linked at about room temperature with water-dispersed polymers such as epoxy, double bond or isothiocyanate containing polymers.
