Abstract
Compounds varying from liquids to solids can be prepared via a reaction in which at least one Michael donor is reacted with one or more Michael acceptors in the presence of an undissolved basic compound as the catalyst.
Claims2
A process which comprises reacting in the presence of an undissolved basic compound as a catalyst at least one Michael donor corresponding to the formula Z'--CH(E)(E") in which Z' is hydrogen, alkyl, or cycloalkyl and E" is hydrogen or an electron withdrawing group is reacted with at least one Michael acceptor corresponding to the formula CTT'=CT"G to form product molecules corresponding to the formula Z--C (E) (E').sub.p --Q.sub.s in which Z is alkyl, cycloalkyl, or --(CTT'--CT"G).sub.w --CTT'--CHT"G;
- Q is --(CTT'--CT"G).sub.t --CTT'--CHT"G;
- p is zero or one;
- s is respectively two or one;
- and each of t and w represents zero or a positive integer such that the compound contains at least acceptor moiety--T, T' and T" in the above formulas being independently selected from hydrogen, G', and organic groups of up to 20 carbons;
- and E, E', G, and G' being independently selected from electron withdrawing groups.
