The present invention relates to curable polyurethane polymers made from renewable materials. In particular isosorbide derived from glucose is used. These renewable materials may be formed into curable polyurethane polymer compositions having different chemical functionalities and cure mechanisms.

(Meth)acrylate-functionalized extended isosorbide

The present invention relates to (meth)acrylate-functionalized waxes and curable compositions, such as anaerobic adhesive compositions, made therewith.

(Meth)acrylate-functionalized waxes and curable compositions made therewith

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

The present invention relates to liquid dual curing (moisture) and photocuring adhesives which are optically transparent/clear. More particularly, the present invention relates to liquid optically transparent/clear adhesives having at least one photo- and/or heat-curable polyolefin-based oligomer, with or without a moisture-curable polyolefin-based oligomer; a curative package to trigger and/or accelerate cure of the oligomer(s) under appropriate cure conditions; and at least one polyolefin-based polyurethane that is not reactive under the cure conditions with the photo- and/or heat-curable polyolefin-based oligomer or the moisture-curable polyolefin-based oligomer. The present invention also relates to optical assemblies that include such optically clear adhesives.

Dual curing optically transparent adhesive 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

An anaerobically curable composition comprising an anaerobically curable component that is a combination of a solid resin component and a solid anaerobically curable monomer. A curing component for curing the anaerobically curable component is included. The composition is solid and has a melting point in the range from 30&#xb0; C. to 100&#xb0; C. The composition is dry to touch and can be used to form articles of manufacture such as a tape, an elongate filament, a gasket, a patch.

Anaerobically 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.

The present invention relates to multi-functional polymeric resin blends which have a defined average molecular weight distribution. Additionally each polymeric component of the blend has a polydispersity of from about 1.01 to about 2.50. The average functionality of the blend is from about 1.8 to about 4.0. More particularly, the present invention relates to poly(meth)acrylates having three or more functional groups. These highly functionalized resin blends are desirably prepared using controlled free radical polymerization techniques, such as single electron transfer living radical polymerization (SET-LRP) processes to produce a variety of blended resin systems which have tailored and enhanced properties.

The present invention relates to novel amine terminated cycloaliphatic polysiloxanes, and preparations thereof. More particularly, the invention provides several reaction schemes for the synthesis of amino-functionalized cyclo-aliphatic silicones and the products produced by the reaction schemes. In one embodiment of the invention, an amine functionalized silicone is prepared through a base-catalyzed ring-opening reaction. In another embodiment of the invention, an amine functionalized silicone is prepared through the hydrosilation of a silicone oligomer through the blocking and deblocking of an amine terminated in a vinyl group.
