Abstract: A method of making a resin composition is described comprising providing a mixture of boron nitride particles and cellulose nanocrystals and combining the mixture with a resin composition. The weight ratio of boron nitride to cellulose nanocrystals typically ranges from 99.9:0.1 to 90:10. The resin composition can have a viscosity at least a 5, 10, 15, 20 or 25% lower than the same composition without the cellulose nanocrystals, which facilitate processing efficiency and is also amenable to incorporating higher boron nitride concentrations into the resin composition. Also described is a (e.g. powder) composition comprising premixed boron nitride particles and cellulose nanocrystals and resin composition comprising such (e.g. powder) composition.

Abstract: Curable and cured compositions are provided that can contain a significant amount of a renewable material based on vegetable oil. More particularly, the curable compositions contain an acid-modified epoxidized vegetable oil (acid-modified EVO) and a (meth)acrylic copolymer having pendant carboxylic acid groups. When the curable composition is reacted to form a cured composition, the acid-modified EVO, which contains greater than one epoxide group per molecule, functions to crosslink the (meth)acrylic copolymer by reacting with the pendant carboxylic acid groups. If the (meth)acrylic copolymer is elastomeric, the cured composition can be a pressure-sensitive adhesive.
