Copolymers comprising recurring units of a phenyl glycidyl ether and alkylene oxides are disclosed. Some of the copolymers comprise a di- or polyfunctional nucleophilic initiator and recurring units of the phenyl glycidyl ether and an alkylene oxide. The di- or polyfunctional nucleophilic initiator is an alcohol, phenol, amine, thiol, thiophenol, sulfinic acid, or deprotonated species thereof. Other copolymers comprise a monofunctional nucleophilic initiator selected from thiols, thiophenols, aralkylated phenols, sulfinic acids, secondary amines, C10-C20 terpene alcohols, and deprotonated species thereof. Pigments dispersions comprising the copolymers are also disclosed. The copolymers meet the growing needs of the industry with their ease of manufacture, diverse structures, and desirable performance attributes for dispersing a wide range of organic and inorganic pigments. Agricultural applications for the copolymers are also disclosed. L'invention concerne des copolymères comprenant des unités récurrentes d'un éther phényl glycidique et d'oxydes d'alkylène. Certains de ces copolymères comprennent un initiateur nucléophile di- ou polyfonctionnel et des unités récurrentes de l'éther phényl glycidique et un oxyde d'alkylène. L'initiateur nucléophile di- ou polyfonctionnel est un alcool, un phénol, une amine, un thiol, un thiophénol, un acide sulfinique, ou une espèce déprotonée de ceux-ci. D'autres copolymères comprennent un initiateur nucléophile monofonctionnel choisi parmi les thiols, les thiophénols, les phénols aralkylés, les acides sulfiniques, les amines secondaires, les alcools terpéniques C10-C20, et les espèces déprotonées de ceux-ci. L'invention concerne également des dispersions de pigments comprenant les copolymères. Ces copolymères répondent aux besoins croissants de l'industrie du fait de leur facilité de fabrication, de leurs structures diverses, et de leurs attributs de performances recherchés pour disperser une large gamme de pigments organiques et inorganiques. L'invention concerne également des applications agricoles de ces copolymères.
