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.

Laser direct writing

A conductive metal-filled substrate is formed by intermingling copper or nickel particles into the substrate, contacting the metal particles with a specified developing agent, and heating the metal particles and the developing agent. The filled substrates are electrically conductive and are useful for a variety of uses such as EMI shielding.

Conductive metal-filled composites via developing agents

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.

Dialkyl dicarbonates as blowing agents for polymers

A conductive-metal-filled substrate is formed by intermingling oxide coated, non-conductive copper or nickel particles into a substrate having a softening point of at least 200.degree. C. followed by compression molding at a temperature of at least 200.degree. C. The filled substrates are electrically conductive and are useful for a variety of uses such as EMI shielding.

Method of making conductive metal-filled substrates without developing

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. 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.

A conductive metal layer is formed on a substrate by depositing copper or nickel particles on the substrate, contacting the metal particles with a specified developing agent, and heating the metal particles and the developing agent. The coated substrates have conductive surfaces and are useful for a variety of uses such as EMI shielding and printed circuit boards.

Conductive metallization of substrates via developing agents

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).

Bicyclic phosphate ether, ester, and carbonate intumescent flame

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.

Flame resistant organic substances containing polymeric flame retardants

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.
