Hybrid copolymers also include a synthetic portion derived from at least one ester monomer and a naturally derived hydroxyl containing chain transfer agent as an end group. Ester graft copolymers include a naturally derived hydroxyl moiety backbone and side chains derived from at least one ester monomer. Further, a method of determining the concentration of a hybrid copolymer in an aqueous system and methods of preparing a hybrid copolymer are also included.
