Abstract
An aqueous dispersion of a segmental copolymer, wherein the aqueous dispersion has a Hard/Soft Balance Advantage value of at least 25% is disclosed. A method for preparing the aqueous dispersion of a segmental copolymer is also disclosed, as is a film produced thereby.
Claims22
An aqueous dispersion, comprising at least one segmental copolymer, wherein said aqueous dispersion has a Hard/Soft Balance Advantage value of at least 25%.
A method of forming a film comprising the steps of:
- (a) forming an aqueous dispersion of a segmental polymer;
- (b) applying said aqueous dispersion to a substrate;
- and
- (c) drying, or allowing to dry, said applied aqueous dispersion;
- wherein said aqueous dispersion has a Hard/Soft Balance Advantage value of at least 25%.
2 more elements
A method of forming a film comprising the steps of:
- (a) forming an aqueous dispersion comprising a plurality of comb copolymer particles:
- wherein said comb copolymer particles comprise a comb copolymer;
- and
- wherein said comb copolymer comprises a backbone and at least one graft segment attached thereto;
- (b) applying said aqueous dispersion to a substrate;
- and
- (c) drying, or allowing to dry, said applied aqueous dispersion;
- wherein said aqueous dispersion has a Hard/Soft Balance Advantage value of at least 25%.
