Abstract: A method for providing a conductive metal deposit on the surface of a dielectric substrate by applying a composition comprising a mixture of a salt and amine or amide compound to the substrate and subjecting the composition to a continuous wavelength laser beam.

Abstract: A method of using blowing agent compositions to produce foamed plastics such as polyurethanes, polyesters and the like, wherein a major auxiliary source of blowing agent for the foam is the decomposition of dialkyl dicarbonates. The dialkyl dicarbonates can be decomposed over temperatures ranging from about 10.degree. C. to about 45.degree. C. when used in combination with particular tertiary amine decomposition catalysts.

Abstract: A conductive metal layer is formed on a substrate having a softening point above about 200.degree. C. by depositing copper and nickel particles having a substantially continuous oxide coating thereon on the substrate, and heating and pressing the metal particles at a temperature of at least 200.degree. C. Unlike similar methods wherein oxide coated metal particles are used, no developing agent is required to render the metal layer conductive. The coated substrates are useful for a variety of uses such as EMI shielding and printed circuit boards.

Abstract: The present invention pertains to a composition of matter and to a method of using the composition to produce foamed plastics, wherein a major, auxiliary source of blowing agent for the foam is the decomposition of dialkyl dicarbonates.

Abstract: A flame resistant composition has (1) an organic polymeric substance (such as polypropylene) in intimate contact with (2) an ether, ester, or carbonate derivative of a bicyclic phosphorous compound (such as pentaerythritol phosphate) and (3) a gas producing compound (such as melamine or ammonium polyphosphate).

Abstract: A flame resistant organic substance comprising an organic substance having intimate contact therewith a flame retarding amount of a flame retardant compound of the formula: ##STR1## wherein each X is independently Cl, or Br, each Z is independently Cl, Br, or H and n is sufficiently high that the compound will be sufficiently nonvolatile that it is capable of retarding the tendency of the substance to flame.

Abstract: The present disclosure relates to novel compounds of the formula: ##STR1## where Y is a hydrogen atom or a metal group and p=1 or 2, and when p=1, ##STR2## n=2, 3, 4 or 5 and n+r.ltoreq.5 and when p=2, ##STR3## m=2, 3 or 4 and m+s.ltoreq.4 and q=0 or 1, where R represents a lower alkyl group containing 1 to 3 carbon atoms, and when q=1, A has the meaning of a substituted or unsubstituted alkylidene group containing 1 to 3 carbon atoms, SO.sub.2, S or O; fire retardant polymer compositions in which these compounds are incorporated, and shaped articles that are entirely or partly made up of such fire retardant polymer compositions.
