Abstract: Curable silicone caulking compositions are provided, employing an ionically polymerized silicone emulsion, a tetrafunctional organosilane, a tin condensation catalyst, calcium carbonate and tetramethylbutylguanidine, as a shelf stabilizer.

Abstract: A composition useful for molding into articles such as food containers, soft drink bottles, cured structural plastics and the like, comprising molding grade linear or unsaturated polyester or polycarbonate having reacted or copolymerized therein the residue of one or a mixture of styrylbenzazole reactants of the formula: ##STR1## wherein A is the residue of a benzene ring of a benzoxazole, benzothiazole or benzionidazole radical; X is --O--, --S-- or --N(R.sup.2)--; Ph is a phenylene radical; and R.sup.1 is halogen or --Y--R.sup.2 in which Y is --O-- or --N(R.sup.2)-- and each R.sup.2 is hydrogen, alkenyl or an unsubstituted or substituted alkyl, cycloalkyl or aryl radical.

Abstract: The process for preparing polyurethanes by the reaction of a bicyclic amide acetal and a polyisocyanate in the presence of a plasticizer such as dioctyl phthalate and a polyurethane catalyst such as stannous octoate is described.

Abstract: Graft polymer dispersions in a polyol are prepared by a continuous process employing in situ free radical polymerization of an ethylenically unsaturated monomer in a polyol containing from about 0.001 to 0.09 mole of induced unsaturation per mole of polyol in the presence of an effective amount of a chain transfer agent. Products prepared by this process have uniform viscosity with resulting product uniformity. Polyurethane foams incorporating flame retardants prepared from these dispersions readily pass the California No. 117 Flame Test.

Abstract: The present invention relates to a process for the preparation of beads of copolymers bearing reactive groups, by polymerization in suspension in a non-aqueous medium. According to the invention a free radical polymerization is effected of at least two unsaturated monomers, of which one is the carrier of a reactive group such as acid chloride, alkyl chloride, alkyl dithiobenzoate or carboxyalkyl, in a medium composed of two emulsified, immiscible organic liquids, to form beads of chemically reactive copolymers.

Abstract: Copolymer polyols are prepared by polymerizing an ethylenically unsaturated monomer in a polyahl mixture in the presence of iodine or an iodine-releasing inorganic compound. The use of the iodine or iodine-releasing inorganic compound provides a lower viscosity, more stable copolymer polyahl.

Abstract: The present invention relates to new modified azulmic acids, several processes for their preparation and their use as intermediate products for the synthesis of numerous products.

Abstract: An adhesive binder composition is provided for the preparation of lignocellulosic composite molded articles such as flake or particle board, made from moldable compositions which comprises an organic di- or polyisocyanate and a liquid dialkyl ester of carbonic acid and optionally lignin, for application to the lignocellulosic material prior to the molding process to form the composite product.

Abstract: The applicants have provided laminates prepared by (a) impregnating a glass fabric with an N-methyl-2-pyrrolidone solution of a compound having the structure of Formula A shown in FIG. 1 of the drawings, (b) heating the impregnated glass fabric to remove solvent therefrom and to covert the amic acid groups to imide groups, and (c) assembling a plurality of the impregnated glass fabrics from (b) and heating the assembly under pressure to a temperature in the range of 177.degree.-260.degree.
