1. A method for styling hair comprising the steps of placing said hair in a desired configuration and applying a composition to said hair, said composition comprising
(a) one or more fully soluble polymers, (b) solvent-propellant mixture comprising
(i) 0% to 75% by weight, based on the weight of said solvent-propellant mixture, propellant,(ii) 5% to 95% by weight, based on the weight of said solvent-propellant mixture, volatile organic solvent, and(iii) 0% to 50% by weight, based on the weight of said solvent-propellant mixture, water, (c) neutralizer, wherein a mole ratio of said neutralizer to the acid-functional groups on said polymer (a) is from 0:1 to 1.1:1, and (d) one or more adjuvants, wherein the ratio of a total weight of all adjuvants to the weight of said polymer (a) is from 0:1 to 1.4:1, wherein an amount of said polymer (a) is 1% to 10% by weight based on a sum of the weights of said polymer (a) and said solvent-propellant mixture (b), wherein an amount of said solvent-propellant mixture (b) is 90% to 99% by weight based on a sum of the weights of said polymer (a) and said solvent-propellant mixture (b), and wherein said (a), (b)(i), (b)(ii), (b)(iii), (c), (d), and any additional ingredients in said composition are chosen so that said composition has Volatile Organic Compounds content of 70% to 95% by weight based on a total weight of said composition, wherein said polymer is made by a method comprising emulsion polymerization of one or more monomer mixtures, wherein said monomer mixtures comprise
(i) 30% to 75% by weight, based on the weight of said monomer mixture, one or more vinyl aromatic monomers that have a refractive index of 1.490 or higher, selected from the group consisting of styrene, alpha-methyl styrene, and mixtures thereof,(ii) 1% to 30% by weight, based on the weight of said monomer mixture, one or more acid-functional monomers, wherein each said acid functional monomer has one or more acid-functional groups, and(iii) 5% to 69% by weight, based on the weight of said monomer mixture, one or more additional monomers, wherein said emulsion polymerization is conducted partially or entirely in the presence of one or more nonionic surfactants and one or more chain transfer agents, wherein said chain transfer agent comprises t-dodecyl mercaptan. |
