摘要： A process for the preparation of water-dilutable polyvinylbutyral dispersions by (1) reacting an aliphatic acid having from one to three isocyanate-reactive groups and from one to three acid groups, or a mixture of such acids, with one or more polyfunctional isocyanates whose average functionality is at least two, where the quantity of the isocyanate component is chosen such that the ratio of the number of isocyanate groups to the number of isocyanate-reactive groups of the acid component is between 2.2:1 and 1.7:1; (2) then reacting from 25 to 75% of the remaining isocyanate groups with at least one monofunctional compound selected from monoalcohols and monoamines; and (3) reacting this NCO-functional emulsifier resin further with polyvinylbutyral and, if desired, with an appropriate plasticizer resin using a suitable auxiliary solvent. The polyvinylbutyral dispersions prepared in this way can be used as binders and binder components for coatings with good adhesion.

摘要： Water-dilutable polyvinylbutyral dispersions obtainable by a two-stage reaction in the first stage of which at least one tertiary alkanolamine A and at least one diisocyanate B are reacted to the theoretically calculated NCO content and the amounts of components A and B are chosen such that the amount of substance of the diisocyanates B is from 0.8 to 1.3 times the amount of substance of the reactive hydroxyl groups in A and thereafter in the second stage a polyvinylbutyral C dissolved in a solvent which is inert towards isocyanates is reacted with the adduct AB from the first step to form the product ABC until all of the isocyanate groups have undergone complete reaction, the number of hydroxyl groups in C being at least ten times the number of isocyanate groups in the reaction product AB.
