Abstract

Polymers are prepared fromA) 60 to 95 percent by weight of a mixture includingA1) 20 to 70 percent by weight of hydroxyalkyl amino triazines andA2) 30 to 80 percent by weight of bis(hydroxyalkyl) amino triazinesB) 5 to 40 percent by weight of polyfunctional compounds selected from one or more ofB1) polyisocyanates and/or oligomeric polyesters or polyethers with isocyanate end groups,B2) aliphatic dicarboxylic acids, esters, chlorides or anhydrides, or aromatic polybasic acids, esters, chlorides or anhydrides,B3) aliphatic or aromatic diglycidal compounds or triglycidyl compounds, and, optionally,C) 1 to 20 percent by weight of aliphatic, cycloaliphatic or aromatic dihydroxy compounds, polyalkylene glycols and aliphatic aldehydes.
