Reaction Conditions

Reaction Steps

A mixture of 350 g of DMAPMA and 280 g of chlorododecene (1.5:1) was stirred with 111.2 g of water (15%) and 6 drops of concentrated sulfuric acid. The reaction mixture was heated up to 95° C. and air was bubbled through it. The conversion was followed by chloride titration. After 24 hours the reaction was completed and the mixture was cooled off. The product is water miscible and is a mixture of 15.0% water; 69.1% MAPLDMAC and 15.9% DMAPMA. It was further used in polymerization without purification.
