PROCESS FOR PREPARING MICHAEL ADDITION PRODUCTS

摘要

Dialkyl malonate/alkyl acrylate Michael addition product mixtures at least three acceptor moieties in a substantial number of the molecules can be consistently prepared without the need for long reaction times of the use of a large excess of the acceptor when the reaction is effected by gradually adding one molar proportion of the dialkyl malonate to at least three molar proportions of an alkyl acrylate which has been preheated to 60-80 .degree.C in admixture with an initiator and a phase transfer catalyst. In a preferred embodiment, the preheated mixture is maintained at 60-80 .degree.C for at least one hour before the dialkyl malonate is added in order to increase the percentage of product composed of the heavier components.
