The disclosure relates to polymers including one or more 1,1-disubstitued alkene monomers. By employing a plurality of monomers and/or tailored chain structure, polymers having improved combinations of properties are achieved. The polymer may be a copolymer, preferably including two or more 1,1-disubstituted alkene monomers. The polymer may be a homopolymer having a tailored chain structure.

A polymerizable system includes a curable composition and one or more encapsulated initiator particles. The curable composition can include one or more 1,1-disubstituted alkene compounds and the encapsulated initiator particles can include one or more polymerization initiators encapsulated by a cured composition.

Disclosed are graft copolymers, compositions including graft copolymers, intermediate materials, and related methods, where the graft copolymer includes a first polymer component including a 1,1-disubstituted-1-alkene compound (preferably a methylene malonate compound) and is grafted to a second component. The resulting graft copolymer may be hydrophilic or water soluble. The second component preferably is a hydrophilic component.

Water absorbing or water soluble polymers, intermediate compounds, and methods thereof

The present teachings are directed at 1,1-disubstituted alkene monomers (e.g., methylene beta-ketoester monomers), methods for producing the same, polymerizable compositions including a methylene beta-ketoester monomer, and polymers, compositions and products formed therefrom. The monomer preferably is a high purity monomer. In the method for producing the methylene beta-ketoesters of the invention, a beta-ketoester may be reacted with a source of formaldehyde. The methylene beta-ketoester monomers may be used in monomer-based products (e.g., inks, adhesives, coatings, sealants or reactive molding) and polymer-based products (e.g., fibers, films, sheets, medical polymers, composite polymers and surfactants).

A class of alkanol amine ligands reacted with bismuth carboxylates lends unique curability properties to isocyanate and polyols for production of polyurethane for CASE applications, including growing demand for polyurethane spray-foam. The amino-alcohol ligand, when associated with bismuth neodecanoate, offers improved moisture and solvent resistance during B-side (polyol) storage, cure rates analogous to tin-based curatives, and overall good final physical properties of the cured polyurethane.

Method to obtain methylene malonate and related monomers following a bis(hydroxymethyl) malonate pathway. A bis(hydroxymethyl) malonate intermediary is subsequently reacted (i.e., subjected to thermolysis) to provide a methylene malonate monomer species. A source of formaldehyde (e.g., formalin) is provided in the presence of a basic catalyst (e.g., calcium hydroxide), to which a malonate (e.g., diethyl malonate) is added under suitable reaction conditions to obtain the desired intermediary (e.g., dialkyl bis(hydroxymethyl) malonate). The intermediary is reacted (i.e., subjected to thermolysis) under suitable conditions in the presence of a suitable catalyst (e.g., a zeolite) to obtain a methylene malonate monomer. In an exemplary embodiment, the thermolysis reaction includes the addition of the bis(hydroxymethyl) malonate intermediary onto a heated catalyst. The reaction product is collected and purified. The disclosed methods may be performed in a continuous operation. Discrete steps may be performed by using modular units within a plant.
