Abstract
Hybrid copolymers for use as anti-scalant and dispersant. The polymers are useful in compositions used in aqueous systems. The polymers include at least one synthetic monomeric constituent that is chain terminated by a naturally occurring hydroxyl containing moiety. A process for preparing these hybrid copolymers is also provided.
Claims26
A hybrid copolymer comprising:
- a synthetic polymer and
- a naturally derived hydroxyl containing chain transfer agent as the end group.
A formulation comprising:
- a hybrid copolymer and at least one adjunct ingredient, wherein the hybrid copolymer is a synthetic polymer and
- a naturally derived hydroxyl containing chain transfer agent as the chain terminating moiety.
A method of cleaning a surface, the method comprising a step of contacting the surface with a cleaning formulation comprising:
- (a) an effective amount of hybrid copolymer comprising a synthetic polymer and
- a naturally derived hydroxyl containing chain transfer agent as the chain terminating moiety and
- (b) an adjunct ingredient.
A method for controlling scale in an aqueous system, the method comprising introducing in to the aqueous system an effective amount of a hybrid copolymer comprising a synthetic polymer and
- a naturally derived hydroxyl containing chain transfer agent as the chain terminating moiety.
A method for dispersing particulates in an aqueous system, the method comprising adding to the aqueous system a hybrid copolymer in an amount sufficient to disperse the particulates wherein the hybrid copolymer comprises a synthetic polymer and a naturally derived hydroxyl containing chain transfer agent as the chain terminating moiety.
