Abstract: In some aspects, the disclosure relates to thermoset polymeric compositions consisting of functional bio-based epoxies and/or their derivatives (e.g. epoxidized vegetable oil(s)), along with carboxyl functional acrylics and/or polyesters. When cured, example compositions yield high performance products suitable for composite, coating, adhesive, sealant, and/or elastomer applications. When used in stone composite formulations with suitable fillers like quartz and titanium dioxide, example products have high hardness, very low water absorption, and high mechanical strength along with stain, chemical, and heat resistance. When used in coating formulations, example cured films have excellent adhesion, high gloss, clarity, toughness, low water absorption, solvent and chemical resistance, flexibility, and impact resistance without compromising hardness. Coating formulation properties may also include exterior durability. The composition properties may be selectively modified to hard, soft, tough, or elastomeric by selecting the appropriate stoichiometry and type of functional resin to react with epoxy(ies)/derivative(s).

Abstract: Provided are surface treatment agents that enable surfaces with a chemically fixed lubricant to be produced instead of a resin coating which has drawbacks, such as that lubricity is reduced due to separation, peeling or the like of the coating during the movement within a vessel or tube; and medical devices, such as catheters, having a surface at least partially treated with such a surface treatment agent. The present invention relates to a surface treatment agent for medical devices which contains a copolymer of a hydrophilic functional group-containing monomer and an epoxy group-containing monomer.

Abstract: The invention herein is a non-aqueous solvent free process for producing UV curable adhesive and sealant compositions comprising a tackifying resin and a monohydroxylated epoxidized polydiene polymer which is comprised of at least two polymerizable ethnically unsaturated hydrocarbon monomers wherein at least one is a diene monomer which yields unsaturation suitable for epoxidation and wherein the polymer contains from 0.1 to 7.0 milliequivalents of epoxy per gram of polymer. The process involves mixing the components with an insoluble photoinitiator under conditions of high shear and/or cavitation. The invention also relates to a film of 5 mils to one inch thick which is formed from the composition made according to the process above.
