The present invention provides thermosetting aqueous binder compositions of one or more cyclic enamine, including bis-enamines and di- or higher functional enamines, optionally containing a water soluble or dispersible or dispersible primary amine compound. The binders are at least substantially formaldehyde free, need no polycarboxylic or polycarboxylate component, and yet provide excellent hot wet tensile strength when cured for as little time as a minute or less in use.

Meta-block copolymers and a process for preparing a product mixture comprising meta-block copolymers by contacting a metathesis catalyst under metathesis conditions with a composition comprising two or more ethylenically unsaturated polymers, said unsaturation defining one or more polymer segments in each ethylenically unsaturated polymer, at least one polymer segment in at least one ethylenically unsaturated polymer being chemically distinguishable from at least one polymer segment in at least one other ethylenically unsaturated polymer, characterized in that each meta-block copolymer in the product mixture comprises a random distribution of said chemically distinguishable polymer blocks.

Production of meta-block copolymers by polymer segment interchange

Two or more chemically distinguishable ethylenically unsaturated polymers, at least one having from 0.001 to 50 mole percent unsaturation and at least one other having an expected Tg or measured Tm value greater than 100&#xb0; C. are cross-metathesized to form thermoplastic elastomers having improved performance properties.

This disclosure relates to olefin polymerization catalysts and compositions, their manufacture, and the production of polyolefins using specific catalyst compositions, including the use of chain shuttling agents in the olefin polymerization process. Specifically, this disclosure provides for dual headed and multi-headed chain shuttling agents (CSAs or MSAs) and for their use in preparing blocky copolymers. By controlling the ratio of dual-headed and multi-headed CSA sites to mono-headed CSA sites, a blocky copolymer can be provided having properties such as a narrow molecular weight distribution and/or improved melt properties.

A fabricated article (e.g., jacketed or insulated wire or cable) is prepared by a process comprising the steps of: applying a coating of a moisture-curable composition onto a wire or cable; and reacting the moisture-curable composition with water, wherein the moisture-curable composition comprises at least one resin having hydrolysable reactive silane groups and a tin catalyst characterized by the tin having a +4 oxidation state and a bis(alkoxide) ligand. The product of the process includes a wire or cable comprising a jacket, wherein the jacket comprises at least one poly olefin resin having hydrolysable reactive silane groups and a tin catalyst, the tin catalyst having a bis(alkoxide) ligand and characterized by the tin having a +4 oxidation state. The product of the process also includes a wire or cable comprising a jacket wherein the jacket comprises (i) the reaction product of at least one polyolefin resin having hydrolysable reactive silane groups and water, and (ii) at least one tin catalyst, the tin catalyst having a bis(alkoxide) ligand and characterized by the tin having a +4 oxidation state.

An olefin metathesis process for converting a reactant olefin or a mixture of reactant olefins into one or more product olefins that are different from the reactant olefin(s). The process employs a catalyst system containing a carbene-generating agent and a bimetallic ruthenium complex comprising one or more &#x3bc;-hydrido bridging ligands, and optionally containing di(t-butyl)phosphine. The catalyst system is advantageously active at process temperatures greater than 90&#xb0; C. Cyclization metathesis and ring-opening polymerization metathesis are preferred olefin metathesis processes.
