| abstract |
The invention relates to copolymers comprising repeating units of a phenyl glycidyl ether and alkylene oxides. Some of these copolymers comprise a di- or polyfunctional nucleophilic initiator and repeating units of phenyl glycidyl ether and an alkylene oxide. The di- or polyfunctional nucleophilic initiator is an alcohol, a phenol, an amine, a thiol, a thiophenol, a sulfinic acid, or a deprotonated species thereof. Other copolymers include a monofunctional nucleophilic initiator selected from thiols, thiophenols, aralkyl phenols, sulfinic acids, secondary amines, C10-C20 terpene alcohols, and deprotonated species thereof. The invention also relates to pigment dispersions comprising the copolymers. These copolymers meet the growing needs of the industry due to their ease of manufacture, their diverse structures, and their desired performance attributes to disperse a wide range of organic and inorganic pigments. The invention also relates to agricultural applications of these copolymers. |
