    摘要： Multi-modal vinyl ester resins having one or more of good fracture toughness, good processing viscosity, and low volatile organic compound emissions are provided. The multi-modal vinyl ester resins are the reaction product of a liquid or crystalline epoxy and an amorphous, solid epoxy, as determined at 25° C., with a vinyl carboxylic acid. The multi-modal vinyl ester resins may contain a reactive diluent, though generally, lower reactive diluent contents are required for such resins than for similar, commercially available vinyl ester resins.

    摘要： An aqueous dispersion comprising a copolymer which is the polymerization product of a mixture of vinylic monomers wherein from about 5% to about 90% by weight of the vinylic monomers are selected from co-esters of a drying oil acid and an unsaturated &agr;, &bgr;-polymerizable unsaturated carboxylic acid, contains from about 0.5% to about 50% by weight based on the weight of the copolymer of a hydrophobic ester or partial ester of a drying oil acid and a polyol. The copolymer polymerized in the presence of the hydrophobic ester or partial ester is characterized by a relatively low gel content, and by a relatively broad, multi-nodal, molecular weight distribution, including a low molecular weight component which acts as a transient plasticizer and coalescing agent. The aqueous dispersions can be formulated into quick drying coating compositions which form smooth protective films on various substrates, without requiring volatile coalescing agents.
