    摘要： A method of preparing a carbamate functional polymer or oligomer is provided. The method comprises: (a) preparing a reaction mixture comprising a lower alkyl carbamate, a hydroxyl functional polymer or oligomer, and an alcohol different from and having a higher boiling point than an alcohol from which the lower alkyl carbamate is derived; and (b) heating the reaction mixture to form a carbamate functional polymer or oligomer. Also provided is a method of preparing a carbamate functional acrylic polymer by preparing a similar reaction mixture using acrylic monomers containing hydroxyl groups or groups that can be converted to hydroxyl groups and heating the reaction mixture in the presence of a free radical initiator and an esterification catalyst.

    摘要： A method of preparing an organic sol of particles is provided. Steps include: a) providing a suspension of particles in an aqueous medium; b) adding an organic liquid to form an admixture where the concentration of particles in the admixture is less than or equal to 40 percent by weight; c) maintaining the admixture at a temperature and pressure and for a time sufficient to reduce the water content to less than 30 percent by weight while simultaneously adding a water-compatible organic liquid at a rate sufficient to maintain a concentration of particles in the admixture at less than or equal to 50 percent by weight; and d) adding at least one polymer while maintaining the admixture at a temperature and pressure and for a time sufficient to provide an organic sol of particles comprising 1 percent by weight or less of water.

    摘要： A high solids, organic solvent based, sprayable coating composition which is capable of acid catalyzed crosslinking is composed of an active hydrogen-containing resin, a curing agent present externally and/or internally as a part of the active hydrogen-containing resin; and a catalytic amount of a non-ionic ester of a sulfonic acid. The sulfonic acid ester is represented by the following structural formulas: ##STR1## wherein: Z is a radical selected from the group consisting of amino and an organic radical, said organic radical being connected to the sulfur atom by a carbon atom;W is C.sub.1 -C.sub.18 alkylene, C.sub.2 -C.sub.18 alkenylene;V is C.sub.1 -C.sub.18 alkylene, C.sub.1 -C.sub.18 hydroxyl substituted alkylene, C.sub.2 -C.sub.18 alkenylene, C.sub.2 -C.sub.18 hydroxyl substituted alkenylene; andR.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5 are independently hydrogen or an organic radical.
