摘要:
Coating and bonding agents based on mixtures of acetoacetates of polyvalent metals, diluents, copolymers of polymerizable acetoacetic esters having the general formula WHERE Y is a hydrocarbon radical and R is H or CH3, and acrylic and/or methacrylic esters and/or styrene given hard and clear films which are resistant to weathering and may chemicals.
摘要:
Phosgene is reacted with a polyhydroxy containing compound to form a polychloroformate. The polychloroformate is then reacted with an acrylate containing one hydroxyl group in the presence of an acid acceptor to form the novel complex acrylate esters of this invention. The product is highly radiation-sensitive so that it may be polymerized by ionizing irradiation and forms a coating on plastic substrates which is hard, stain-resistant and abrasion-resistant.

CROSS-LINKABLE ETHYLENICALLY UNSATURATED POLYMER COMPOSITIONS ARE DESCRIBED, WHICH COMPOSITIONS COMPRISE AN ETHYLENICALLY UNSATURATED POLYMER, A PRECURSOR OF A POLYFUNCTIONAL NITRILE N-OXIDE OR NITRILE IMINE AND A LACTONE OR SULTONE. THESE COMPOSITIONS CROSS-LINK WHEN HEATED. SUITABLE LACTONES ARE THOSE CONTAINING 3 OR 4 CARBON ATOMS IN THE LACTONE RING SUCH AS PROPIOLACTONES AND BUTYROLACTONES AND SUITABLE SULTONES ARE THOSE CONTAINING 3 CARBON ATOMS IN THE SULTONE RING SUCH AS 1,3-PROPANE SULTONE. THESE COMPOSITIONS ARE USEFUL AS SEALANTS AND ADHESIVES.

CROSS-LINKABLE POLYMER COMPOSITIONS ARE DESCRIBED WHICH COMPRISE AN ETHYLENICALLY UNSATURATED POLYMER, THE SULTONE ADDUCT OF A TERTIARY AMINE AND A PRECURSOR OF A POLYFUNCTIONAL NITRILE N OR NITRILE IMINE. TYPICAL SULTONE ADDUCTS ARE THE 1,3-PROPANE SULTONE ADDUCTS OF TRIETHYLAMINE, TRIETHYLENEDIAMINE, N-METHYL MORPHOLINE AND QUINUCLIDINE. THESE COMPOSITIONS, WHICH CROSS-LINK ON HEATING, ARE USEFUL AS SEALANTS AND ADHESIVES AND IN COATING COMPOSITIONS.
摘要:
The present invention is directed to novel organometallic complexes as catalysts for the reaction of compounds with isocyanate and hydroxyl functional groups to form urethane and/or polyurethane and the process employing such catalysts. More particularly, the present invention is directed to novel complexes of zinc(II) with substituted amidines. These novel catalysts are useful for the production of urethanes and polyurethanes which are important in many industrial applications.
摘要:
A sheet-like article of polyvinyl chloride which is obtained by calendering a composition comprising polyvinyl chloride, a reactive plasticizer, a photosensitizer, a stabilizer and a polymerization inhibitor, and then irradiating the product with ultraviolet rays.
