Abstract
An aqueous coating composition comprising a comb copolymer is disclosed. A method of forming a coating from the aqueous coating composition, and a coating formed by that method are also disclosed, as is a method of forming the comb copolymer. The comb copolymer is characterized in that aqueous dispersions of the comb copolymer have a Hard/Soft Balance Advantage value of at least 25%. The aqueous coating composition is capable of producing coatings having an excellent balance of hard and soft properties.
