Aqueous polymer compositions containing glycerol esters as plasticisers

摘要

The present invention relates to aqueous polymer compositions containing a group of glycerol esters that have not previously been described as effective plasticisers for polymer compositions in the absence of other additives. Preferred members of this group of esters exhibited unexpectedly large viscosity increases in aqueous polymer dispersions in addition to effectively reducing the glass transition temperature of the dispersed polymer.
