Production and use of polymers comprising hydroxyl groups and acrylate groups

A polymer, comprising:

• a hydroxyl group;
• and
• an acrylate group;
• wherein:
• the polymer is a reaction product of a dicarbonyl compound with a diacrylate compound;
• the dicarbonyl compound comprises just two carbonyl groups, each independently selected from the group consisting of an aldehyde group and a keto group, bonded to one another through a substituted or unsubstituted C1-C8-alkyl, a substituted or unsubstituted C2-C8-alkenyl, a substituted or unsubstituted carboxy-C1-C8-alkyl, a substituted or unsubstituted C6-C12-aryl, a substituted or unsubstituted C6-C12-arylene, a substituted or unsubstituted C3-C12-cycloalkylene, or a substituted or unsubstituted C1-C20-alkylene;
• and
• the dicarbonyl compound and the diacrylate compound are reacted in the presence of at least one tertiary amine or phosphine selected from the group consisting of trimethylamine, triethylamine, tri-n-butylamine, ethyldiisopropylamine, methyldiisopropylamine, N-methylmorpholine, N-methylpiperidine, triethanolamine, N,N-dimethylethanolamine, 2 dimethylaminopyridine, 4-dimethylaminopyridine, diazabicyclooctane, 1,5 diazabicyclo[4.3.0]non-5-ene (DBN), 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU), pyrrocoline, quinuclidine, quinidine, trimethylphosphine, triethylphosphine, tri-n butylphosphine, dimethylphenylphosphine, and 1,4 diazabicyclo[2.2.2]octane (DABCO).
