  • Patent number: 5162420
    Abstract: Disclosed is an aqueous composition containing a vinyl-type polymer product having hydrolyzable silyl groups which aqueous composition is stable at relatively high solids for such a composition and yet cures at relatively low temperatures upon the evaporation of water. More particularly, disclosed is a stable, aqueous, colloidal silica-free, dispersion or solution containing a solution-polymerized vinyl-type polymer having acid functionality sufficient to provide an acid value of from 5 to 160 and having a hydroxyl value of less than or equal to 10 and sufficient hydrolyzable silyl groups to provide a Si content in the range of from 0.40 to 6.0 percent by weight based on the total weight of the vinyl-type polymer. The vinyl-type polymer is characterized in that a composition consisting of at least 25 percent by weight of the polymer in water remains stable in a closed container for at least 24 hours at a temperature of 48.9 degrees Celsius.

  • Patent number: 4126527
    Abstract: Relatively water insoluble hydroxy functional monoethylenic polyethers or polyesters of monoethylenic carboxylic acids or hydroxy aklys esters thereof are formed by adducting the monoethylenic acid or its hydroxy ester with an anhydride selected from monoepoxides, lactones, or mixtures thereof in the presence of a Lewis acid catalyst, such as BF.sub.3 etherate, at a temperature below that at which the unsaturation is consumed, typically about 30.degree.-70.degree. C. These adducts are of low volatility and of low toxicity and can be radiation cured in admixture with polyacrylates to form coatings having improved resistance to elevated temperature exposure.
