Abstract
Hybrid copolymers for use as anti-sealant 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.
Claims25
A method of preparing a hybrid copolymer comprising combining at least one monomer with a solution of a naturally derived hydroxyl containing chain transfer agent and an initiator that is not a metal based redox system at a temperature effective to activate the initiator.
A method of preparing a hybrid copolymer formulation comprising:
- adding a hybrid copolymer to 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.
