A water tree resistant composition comprising: (a) a thermoplastic resin; grafted with (b) 2-acrylamido-2-methylpropanesulfonic acid.

Tree resistant compositions

Process of producing a foamed product by forming a shaped article from a composition comprising a thermoplastic olefin polymer, a hydrolyzable, unsaturated silane, a gas generating compound and an organic peroxide in an amount of about 0.5 to about 2 percent by weight, and thereafter subjecting the shaped article to elevated temperatures to activate the gas generating compound and organic peroxide.

Process of producing foamed products

The disclosure is directed to water curable polymers of an azide sulfonyl silane and a substantially linear, low pressure ethylene polymer which are resistant to water and electrical treeing and can be used as coverings, such as insulation, about wires and cables.

Water curable, azide sulfonyl silane modified ethylene polymers

The disclosure is directed to preformed, reactive catalysts, which are the reaction products of a mixture containing an organo titanate, a polyol and a monohydric alcohol. These catalysts can be admixed with alkylene-alkyl acrylate copolymers to provide compositions which can be extruded about electrical wires and cables and cured, at improved cure rates, to crosslinked products characterized by improved physical properties.

Reactive organo titanate catalysts

The disclosure of this application is directed to water-curable, azide sulfonyl silane modified, alkylene-alkyl acrylate copolymers which are particularly useful as coverings about wires and cables providing insulation or jacketing thereon having improved elongation properties.

Water curable, azide sulfonyl silane modified, alkylene-alkyl acrylate

The disclosure is directed to a preformed, reactive catalyst, which is the reaction product of a mixture containing an organo titanate, a polyol and a monohydric alcohol. These catalysts can be admixed with alkylene-alkyl acrylate copolymers to provide compositions which can be extruded about electrical wires and cables and cured, at improved cure rates, to crosslinked products characterized by improved physical properties.

Curable compositions, based on alkylene-alkyl acrylate copolymers,

Polysiloxanes prepared by reacting a diester and a monomeric silane and the use of the polysiloxanes to produce silane modified, water-curable copolymers by reacting the polysiloxanes with alkylene-alkyl acrylate copolymers in the presence of an organo titanate catalyst. The copolymers so produced can be extruded about electrical conductors and water-cured providing insulation or jacketing thereon.

Polysiloxanes and the use thereof in the production of silane modified

The disclosure of this application is directed to a composition based on an alkylene-alkyl acrylate copolymer, a polyhydric alcohol and an organio titanate, the cure rate of which can be retarded by the addition thereto of a molecular sieve. The composition disclosed can be extruded about wire and cables providing protective coatings thereon.

Crosslinkable compositions based on alkylene-alkyl acrylate copolymers

Blends of vinyl chloride polymers containing no carboxyl groups and about 10 to about 30 percent by weight of an ethylene/vinyl alcohol copolymer containing greater than 50 mole percent of vinyl alcohol therein provided excellent barrier packaging materials.
