Compositions on a polyurethane basis containing a polymer of an ethylenic oxime, process for the preparation of these compositions and their applications.

摘要

1. Polymer compositions characterized in that they comprise : - a polyurethane, such as is obtained by reaction of (a) a chain lengthener which is a primary diamine, with (b) a prepolymer, containing terminal isocyanate groups, based on a hydroxylic polybutadiene, polyester or polyether, of which the isocyanate functions are blocked by an unsaturated vinyl ketoxime, and - a polymer of the said unsaturated vinyl ketoxime.
