The present invention relates to curable polyurethane polymers made from renewable materials and having polymerization accelerator groups built into the polymer. In particular hydroxylated oleaginous materials derived from plant oils, such as soybean oil, are used. These renewable materials may be formed into curable polyurethane polymers having different chemical functionalities and cure mechanisms.

Functionalized accelerating resins derived from renewable materials

Copolymers prepared by a reaction of (1) an unactivated olefin, (2) an activated olefin, and (3) a hydroxyl functional activated olefin and/or a hydroxyl functional unactivated olefin are described. The copolymers have a backbone of polar vinyl monomers and non-polar alkene monomers, with pendant hydroxyl functional groups. The copolymers are well suited for optically clear, pressure sensitive, polyurethane and/or barrier adhesives.

Olefin-acrylate copolymers with pendant hydroxyl functionality and use thereof

This invention relates to photocurable electron deficient olefin-containing compositions, such as those containing certain 2-cyanoacrylates, 2-cyanopentadienoates, methylidene malonates, and vinylidine cyanide, and photolatent bases. When exposed to radiation in the electromagnetic spectrum, the compositions show a delay cure property.

Photocurable electron deficient olefin-containing compositions

The invention provides reactive resins compounds and compositions made from renewable materials, such as plant and animal oils. The reactive resins compounds and compositions may include an accelerator as part of their structure and are made from renewable materials containing a variety of functional groups. The compositions provide excellent adhesion and sealing capability.

Reactive resins made from renewable sources

Disclosed is a simplified process for formation of polyisobutylene functionalized with at least one terminal primary or secondary alcohol. The process comprises subjecting an olefin functional polyisobutylene, butyl rubber, or mixtures thereof to ozonation and reduction thereby forming mono-alcohol and diol functional polyisobutylene. The formed functional polyisobutylenes can serve as precursors for many other functionalized polyisobutylenes including urethane polyisobutylenes, urethane polyisobutylenes capped with (meth)acrylate functions, and (meth)acrylate capped polyisobutylenes.

Synthesis of functionalized polyisobutylenes

Benzoylthiourea or benzoylthiourethane derivatives as cure accelerators for two part curable compositions are provided.

Accelerators for two part curable compositions

A method of preparing high molecular weight poly(meth)acrylate polymers having narrow polydispersity indices (PDIs) by coupling poly(meth)acrylate building block units which themselves have narrow PDIs. The building block units have halogenated terminations, which when reacted with selected coupling agents, from the high molecular weight poly(meth)acrylate polymers.

A process for preparing moisture curable compounds and moisture curable compositions prepared from the product of that process is provided.

Alkoxysilane-functionalized hydrocarbon compounds, intermediates thereof and methods of preparation thereof

The present invention relates to anaerobic curable compositions, such as adhesives and sealants, containing blocked acrylic acid compounds. The blocked acrylic acid compounds are labile (meth)acrylic acid compounds having an acetal linkage, which cleaves to release (meth)acrylic acid during anaerobic cure. In this way, the block acrylic acid compounds acts as an adhesion promoter thereby promoting adhesion to various substrates.

Anaerobic curable compositions containing blocked (meth)acrylic acid compounds

Anaerobic curable compositions, such as adhesives and sealants, containing blocked carboxylic acid compounds are provided. The blocked carboxylic acid compounds are labile carboxylic acid compounds having acetal linkages, which cleave to release the underlying carboxylic acid during anaerobic cure.

Anaerobic curable compositions containing blocked (meth)acrylate acid compounds

Anaerobic curable compositions, such as adhesives and sealants, containing blocked dicarboxylic acid compounds are provided. The blocked dicarboxylic acid compounds are labile dicarboxylic acid compounds having two acetal linkages, which cleave to release the underlying dicarboxylic acid during anaerobic cure. In this way, the dicarboxylic acid can participate in the anaerobic cure of the composition when the blocking group is released.

Anaerobic curable compositions containing blocked dicarboxylic acid compounds

Disclosed are reactive functionalized, PIB grafted polymers having an architecture of one or more pendent polyisobutylene moieties grafted on to an organic backbone, wherein the backbone is not polyisobutylene and contains at least one telechelic, reactive functionality. Also a process for making the reactive functionalized, PIB grafted polymer s and curable compositions comprising the reactive functionalized, PIB grafted polymers.
