Dibenzodiazocine polymers, methods for producing dibenzodiazocine polymers, products formed from dibenzodiazocine polymers, and uses for such dibenzodiazocine polymers are provided.

Production of polymers of conjugated dienes and/or vinyl-substituted aromatic compounds utilizing, in said production, polymerization initiator compositions comprising reaction products of C.sub.2 -C.sub.12 alkyllithiums with monomers from the group of polymerizable conjugated dienes and polymerizable vinyl-substituted aromatic compounds in a medium of aliphatic, cycloaliphatic or aromatic hydrocarbons and/or aliphatic tertiary monoamines or aryl ethers, the conjugated diene and vinyl-substitute...

Polymers with high tensile and flexural strength, suitable for molding or milling, are obtained by the reaction of pentaerythritol with a thiadialdehyde or derivative thereof, or by the reaction of a reactive metal sulfide with a 3,9-bis(halomethyl)-spirobi(meta-dioxane) or a similar spiro intermediate. "Copolymers" may be prepared by substituting a salt of a dithiol for the sulfide.

Blended polymer compositions containing random interpolymers of ethylene and 1-vinyl-2-pyrrolidinone.

Production of epihalohydrin polymers using a catalyst system including an organoaluminum compound and sulfur wherein the sulfur/aluminum atomic ratio is from about 0.05 to 0.8.

In the art of electroplating nonconductive materials, adhesion of metal to the material is enhanced by incorporating into the material from 1 to 25 percent by weight of a metal resinate. Crystalline polyolefins, such as polyethylene, polypropylene and propylene-ethylene copolymer, are modified with calcium resinate, zinc resinate, aluminum resinate, sodium resinate, potassium resinate or ammonium resinate to improve the adhesion of metal thereto.

Dissolution of cross-linked polymer gels is effected by use of Lewis acids plus Lewis salts.

Polymers are prepared by condensing a polyhydroxy monocarboxylic acid of formula (OH).sub.n R--COOH, wherein n is an integer from two to six and R is a hydrocarbon radical containing up to 22 carbon atoms to which the hydroxyl groups are attached and optionally interrupted by or containing a hetero atom, with other condensable species which exclude those containing more than one carboxyl group or a group equivalent to more than one carboxyl group. The polymer per se or when attached to another m...

This invention relates to triazapentadiene polymers having at least one triazapentadiene unit of the formula: wherein each X is selected from chlorine and fluorine, each Y is selected from halogen and perhalo lower alkyl, m and n are positive integers greater than zero, x is from 3 to 1 million, --(CXY).sub.m Z(CXY).sub.n-- is a divalent polyhalo organic radical where the sum of m plus n plus the number of equivalent units in Z is at least 4 and Z is at least one member of the group of perhalo l...

Urethane polymers comprising the reaction product of (1) an organic polyisocyanate and (2) the product resulting from the reaction of (a) elemental phosphorus (b) an epoxide or an epithioalkane and (c) an alcohol or an alkanethiol said reaction being carried out in the presence of a catalytic quantity of a base. The aldehyde and/or alkylene oxide treated reaction product when combined with organic polyisocyanate also produce novel urethane polymers.
