The present disclosure provides cashew nut shell liquid derivatives based organosilicon products and methods and uses of preparing the same.

The present invention provides methods, processes, and systems for the manufacture of three-dimensional articles made of polymers using 3D printing. A layer of prepolymer is deposited on a build plate to form a powder bed. The deposited powder bed is heated to about 50 C. to about 170 C. Then, a solution of activating agent is printed on the powder bed in a predetermined pattern, and a stimulus is applied converting the prepolymer to the final polymer. After a predetermined period of time, sequential layers are printed to provide the three-dimensional article. The three-dimensional object can be cured to produce the three-dimensional article composed of the final polymers.

Aspects of the present invention relate to polymers, and particularly to farnesene polymers functionalized with one or more oxirane groups and, optionally, one or more hydroxyl groups. According to one aspect of the invention, provided is an epoxidized and optionally hydroxyl-functionalized polyfarnesene. The epoxidized farnesene polymer has at least one of a side chain or a main backbone functionalized with at least one oxirane group and, optionally, at least one terminal end functionalized with a hydroxyl group. In accordance with another aspect of the invention, a method is provided for preparing an epoxidized and optionally hydroxyl-functionalized polyfarnesene. The method includes epoxidizing a farnesene polymer, which may optionally contain one or more terminal hydroxyl groups, to functionalize at least one of a side chain or a main backbone of the farnesene polymer with an oxirane group.

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).

An adhesive composition containing: an epoxy resin (A) having a fused ring structure; an epoxy resin curing agent (B); a polyrotaxane compound (C); and a polymer component (D), wherein the polyrotaxane compound (C) is contained in a content of 5 to 15 parts by mass based on total 100 parts by mass of contents of the epoxy resin (A) and the polymer component (D); a film adhesive using the adhesive composition; and a semiconductor package and a producing method thereof.

The present application relates to polyurethane polymers produced by polymerizing a reactant mixture comprising triglycerides of Physaria fendleri, one or more polyisocyanates, and one or more polyols, wherein the triglycerides of Physaria fendleri have a hydroxyl value ranging from 90 milligrams of potassium hydroxide per gram of the triglycerides of Physaria fendleri to 250 milligrams of potassium hydroxide per gram of the triglycerides of Physaria fendleri. The present application also relates to polyester polymers produced by polymerizing a reactant mixture comprising triglycerides of Euphorbia lagascae, and one or more dicarboxylic acids. Also disclosed are the methods of formation of the polyurethane and polyester polymers, and their use as adhesives.
