Abstract
The present process is directed to preparation of addition polymers in diluents that are subsequently reactive in coatings during cure, instead of in traditional hydrocarbon solvents. The polymers so prepared can be used as the main film-forming polymer in high solids coating compositions, especially those useful for finishing automobiles and truck exteriors.
Claims8
A process for producing a polymer, said process comprising the step:
- polymerizing at least one ethylenically unsaturated monomer in the presence of a catalyst and a liquid carrier, wherein said liquid carrier is a reactive diluent, said reactive diluent having at least two reactive sites.
A composition comprising;
- (a) at least one ethylenically unsaturated monomer;
- (b) at least one reactive diluent;
- and
- (c) at least one catalyst suitable to catalyze the polymerization of said ethylenically unsaturated monomer;
- wherein said reactive diluent is selected from selected from the group consisting of alkoxy silanes, alkoxy silicates, amide acetals, ketimines, cyclic carbonates, orthoesters, spiro-orthoesters, bicyclic orthocarbonates, or a combination thereof.
