Abstract: A reactive fluorinated polymer having polyester and polyether segments is mixed with a reactive melamine resin to form a coating composition. The polyether segment can include monomeric units from an oxetane monomer having pendant fluorine groups that are linked to the oxetane via an ether group. The melamine resin can be a lower alkyl etherified melamine-formaldehyde. The composition can be disposed on a substrate and treated to form a laminate.

Abstract: An electrically conductive composite comprising conductive polyacetylene moiety, a nonconductive high nitrile resin, and a dopant. The high nitrile resin further comprises at least nitrile monomers or comonomers and optionally copolymerized with comonomers of mono-ethylenically unsaturated monomers and conjugated diolefins and further optionally containing an elastomeric component.The invention further includes a process for producing an electrically conductive composite comprising:(1) impregnating a high nitrile resin with a Zeigler type catalyst comprising an alkyl aluminum compound and alkyl, alkyl halide, halide, oxyhalide or alkoxide of Group IVA and VA metals,(2) exposing the impregnated high nitrile resin with an alkyne under polymerization conditions whereby polymerization occurs to form a polyacetylene/nitrile composite, and(3) adding dopant to the composite.

Abstract: Conjugated dienes are polymerized by a catalyst system comprised of a transition metal complex consisting of at least one binucleating ligand attached to at least one transition metal containing nucleus; and at least one organometallic cocatalyst containing at least one element of Group IA, IIA or Group IIIA.

Abstract: A multiple stage autodeposition of organic polymer coating compositions deposited onto metal substrates wherein the coating composition's thickness does not increase by more than about 20.DELTA. compared to a single dry coating. The coated metal substrates formed by the process of the instant invention are corrosion resistant.

Abstract: A novel transition metal complex catalyst comprised of a transition metal attached to a ligand containing electron withdrawing substituents is employed in a polymerization process for producing nylon type polyamides.

Abstract: A process for producing polyamides comprising contacting a polyamide forming system with a transition metal complex catalyst at a temperature sufficient to cause polymerization. The transition metal complex catalysts are at least one binucleating ligand attached to at least one transition metal containing nucleus.

Abstract: This invention relates to a supported catalyst and to the use of this catalyst in a process for the polymerization of alpha-olefins. The catalyst comprises a transition metal complex supported on an interpolymer comprising an alpha, beta-unsaturated dicarboxylic acid, anhydride or lower alkyl ester thereof, and one or more monomers copolymerizable therewith which has been treated with a Group IIA halide or alkyl halide. Preferred supports comprise maleic anhydride copolymers which have been treated with a magnesium compound.

Abstract: This invention relates to a new supported catalyst and to the use of this catalyst in a process for the polymerization of alpha-olefins. The catalyst comprises a transition metal complex supported on a planar organosilicon polymer which has been derived from at least one of chrysotile and apophyllite. The support is prepared by the leaching of the metal ions from the mineral and substitution of some of the silanol groups with alkyl silyl groups. Particularly active catalysts can be prepared by treating the planar organosilicon polymer with silicon tetrachloride prior to contacting the polymer with a transition metal complex.

Abstract: A process for polymerizing alpha-olefins in the presence of a Ziegler-type catalyst wherein at least one of dichloroethane, dichloropropane and chlorine gas is added to the process after the polymerization has been initiated. This invention is especially useful when the olefin is propylene and the catalyst is a titanium trichloride complex.
