AQUEOUS PIGMENT DISPERSION CONTAINING LOW MOLECULAR WEIGHT POLYTRIMETHYLENE ETHER GLYCOL

The present disclosure is directed to an aqueous pigment dispersion comprising low molecular weight polytrimethylene ether glycol. This disclosure is further directed to an antimicrobial aqueous pigment dispersion comprising the low molecular weight polytrimethylene ether glycol. The pigment dispersion can be used in coating compositions as interior and exterior top coats, basecoats, primers, primer surfacers and primer fillers. The disclosure is particularly directed to an aqueous pigment dispersion comprising components derived from renewable resources.

Preparation of Discrete Oligoethers: Synthesis of Pentabutylene Glycol and Hexapropylene Glycol by Two Complementary Methods

Two experimentally facile methods for the preparation of discrete oligoethers are reported. The first involves an iterative sequence of oxidation, acetal formation, and reductive ring opening for the synthesis of penta-1,4-butylene glycol. The second method is also iterative, comprising phase-transfer etherification and end-group deprotection to form hexa-1,3-propylene glycol. These methods offer significantly improved yields and purification protocols over previously reported syntheses.
