    摘要: Trimerized isocyanates having improved solubility in polyisocyanates are prepared by reacting a polyisocyanate with a low equivalent weight polyol to form a first prepolymer, forming a cotrimer from said first prepolymer by reaction of same with diphenylmethane diisocyanate or polymeric derivatives thereof, and forming a second isocyanate terminated prepolymer by reacting said cotrimer with a second low equivalent weight polyol. The resulting cotrimer can be diluted in a polyisocyanate and used to prepare polymers, particularly polyurethane foams, having excellent properties.

    摘要: This invention provides novel resin systems and high solids, solvent-based chain-extendable, self-crosslinking coating compositions comprising same. The resin systems comprises novel diblocked diisocyanate urea urethane oligomers of molecular weight about 300 to 5000. The resin system further comprises a polyepoxide, preferably a diepoxide, of molecular weight about 100 to 1000 used generally with said oligomer in weight ratio of about 1:1 to about 1:10, respectively. The resin components provide chain-extension polymerization during cure at elevated temperature, in situ, on the surface of a substrate. The resin system is also self-crosslinking. That is, no additional crosslinking component is required to cure the composition. The cured coatings of the invention provide greatly improved physical properties, in particular, greatly improved corrosion resistance.
