Abstract:
Unsaturated polyester compositions are disclosed that are obtainable by reacting: (i) plant and animal oil triglycerides, an alkyl ester of a saturated or unsaturated fatty acid or mixtures thereof; (ii) a difunctional, or polyfunctional glycol or mixtures thereof; (iii) a difunctional or polyfunctional acid, their anhydrides or alkyl esters and mixtures thereof; (iv) a strained cycloolefin; (v) a component(s) that function as a compound capable of initiating polymerization at high temperature and which is stable at room temperature; and (vi) low profile additives, fillers, and reinforcements. Also disclosed are methods for the preparation of the polyesters and the use of the polyesters in closed and open mold compositions such as sheet molding compound (SMC), bulk molding compounding (BMC), resin transfer molding (RTM), pultrusion, infusion, filament winding, and spray up.
Abstract:
The present invention provides a crosslinkable polymer system that can be crosslinked to form a wide variety of polymeric, copolymeric and oligomeric compounds. The crosslinkable system comprises (a) product Q formed from an aromatic ethylenically unsaturated moiety and a first reactive ethylenically unsaturated moiety, and (b) a second reactive ethylenically unsaturated moiety at least partially reacted with the first reactive ethylenically unsaturated moiety.
Abstract:
A laminating resin having low styrene content is provided. The resin includes a thermosetting resin and a reactive intermediate including a low molecular weight polyester oligomer endcapped with at least one (meth)acrylic acid, its ester or its anhydride thereof.
Abstract:
A method of lining a surface of a substrate comprises providing a reactive mixture which comprises (1) a resin containing active hydrogens; (2) a polycarbodiimide; and (3) an organic diluent; reacting the resin containing active hydrogens and the polycarbodiimide to chemically bind the resin and the polycarbodiimide; applying the chemically bound resin and polycarbodiimide to the surface of the substrate; and curing the chemically bound resin and polycarbodiimide in the presence of an initiator to form a cured resin material which lines the surface of the substrate.
Abstract:
A polyetherester-based laminating resin composition includes an unsaturated polyetherester resin, and an epoxy acrylate oligomer. The laminating resin has no greater than about 35 percent by weight of ethylenically unsaturated monomer.
Abstract:
A toner resin composition and a method of making the same are disclosed. The toner resin composition comprises a polyester resin formed from a reaction between a polybasic acid or anhydride and a polyhydric alcohol, and a polyfunctional epoxy resin which is crosslinked to the polyester resin. The crosslinking is effected in the presence of a catalyst.
Abstract:
Methods of making unsaturated polyester compositions are provided and include reacting: (i) plant and animal oil triglycerides, an alkyl ester of a saturated or unsaturated fatty acid or mixtures thereof; (ii) a difunctional, or polyfunctional glycol or mixtures thereof; (iii) a difunctional or polyfunctional acid, their anhydrides or alkyl esters and mixtures thereof; (iv) a strained cycloolefin; (v) a component(s) that function as a compound capable of initiating polymerization at high temperature and which is stable at room temperature; and (vi) low profile additives, fillers and reinforcements.
Abstract:
The present invention provides a thermosetting resin composition based on an orthophthalic unsaturated polymer resin, a dicyclopentadiene (DCPD) resin and a polyether urethane acrylate having two or more acrylate functionality per molecule.
Abstract:
A laminating resin composition is disclosed which comprises an unsaturated polyester resin, a vinyl ester resin, a polyfunctional acrylate, and up to about 15 percent by weight of a vinyl monomer. Preferably, the vinyl ester resin has a molecular weight ranging from about 450 to 1500.
Abstract:
A method of thickening a resin comprises blending (1) a resin containing active hydrogens, such as an unsaturated polyester (2) a polycarbodiimide, and (3) an organic diluent to form a reactive mixture; and reacting the resin containing active hydrogens and the polycarbodiimide such that the resin and polycarbodiimide become chemically bound.
