A silicone polyurethane has a maleimide group at least at a terminal. Thus, the present invention provides: a silicone polyurethane which serves as a material for a stretchable film excellent in stretchability and strength and also in water repellency on the film surface; such a stretchable film; and a method for forming the stretchable film.

The resin composition according to the present invention is a resin composition including a cyanate compound (A) and/or a maleimide compound (B), and an inorganic filler (C), wherein the inorganic filler (C) includes a boron nitride particle aggregate including primary hexagonal boron nitride particles, wherein (0001) planes of the primary hexagonal boron nitride particles are stacked on top of each other to thereby form the boron nitride particle aggregate.

A polyurethane dispersant is described that comprises a reaction product of a polyisocyanate with a) a component supplying a anchoring imide group wherein the carbonyl groups of the imide are bonded to a fused or non-fused aromatic ring, b) at least one solvent-solubilizing chain, and other optional components to build molecular weight or modify the interaction of the dispersant with various particulates or continuous media.

A reaction mixture and production method for making a polyurethane comprising material having reduced aldehyde emissions.

The present invention relates to aqueous peptide-functionalized polyurethane dispersions that can be used as adhesives, in particular for metal surfaces, such as steel surfaces. As hybrid materials, they provide for a versatile system that can be finely tuned and combine the advantageous properties of polyurethane and peptide materials. Also encompassed are processes for their production, compositions containing them and their use as coatings and adhesives.

Polymeric dispersants are disclosed that include a urethane backbone at least one pendantly attached imide group, wherein the carbonyl of the imide are chemically bonded to a single or fused aromatic ring. The aromatic ring can be substituted with various electron withdrawing or releasing groups. The dispersant also includes solvent-solubilizing chains of polyether, polyester, polyacrylate, and or polyolefin Desirably, the imide groups are derived from an imide that has two isocyanate reactive groups such that the imide is attached to the urethane backbone at two separate locations.

The resin composition according to the present invention is a resin composition including a cyanate compound (A) and/or a maleimide compound (B), and an inorganic filler (C), wherein the inorganic filler (C) includes a boron nitride particle aggregate including primary hexagonal boron nitride particles, wherein (0001) planes of the primary hexagonal boron nitride particles are stacked on top of each other to thereby form the boron nitride particle aggregate.

A shape-memory self-healing polymeric network (SMSHP) is useful as a molded part, a coating, or as a matrix for a composite that can be repaired by heating to a controlled temperature. The SMSHP has thermally reversible repeating units where a thermally reversible adduct is situated between two common linking units formed during a polymerization process between thermally reversible monomers and cross-linking monomers. Optionally, other repeating units can be present from other monomers. Shape-memory results when the SMSHP is warmed to a temperature in excess of its glass transition temperature and self-healing then proceeds when a higher temperature is achieved where thermally reversible adducts dissociates to complementary groups that subsequently reform the adduct without distortion of the memorized shape. The thermally reversible adducts can be Diels-Alder (DA) adducts in a polyurethane, poly urea, or amine epoxy SMSHP network.
