Abstract: 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.

Abstract: A modular cooling loop system for cooling a manufacturing process machine connects to a chilled water system and the manufacturing process machine. The cooling loop system includes a movable chassis and a coolant piping loop mounted on the chassis. The coolant piping loop includes a pump, a plurality of coolant inlets a plurality of coolant outlets, a plurality of temperature sensors for measuring coolant temperature in the coolant piping loop, a flow sensor for measuring coolant flow in the coolant piping loop, and a flow control valve for controlling the flow of fresh coolant into the coolant piping loop. The coolant piping loop is configured to recirculate coolant through the coolant piping loop and the manufacturing process machine.
