Abstract: The present invention relates to low glass transition temperature adhesive copolymers useful in products such as those which provide hair styling hold, e.g., aerosol mousses, shampoos and conditioners. The monomer components in these copolymers are randomly distributed in the copolymer chain, preferably to form a substantially linear chain. At least one of the monomer components is selected from acrylate amides and methacrylate amides; and furthermore at least one of the other monomer components is selected from acrylate esters and methacrylate esters. These copolymers have a single glass transition temperature within the temperature range of from about 0.degree. C. to about 80.degree. C. The present invention further relates to hair styling compositions (e.g., aerosol mousses, shampoos, conditioners) comprising these adhesive copolymers, and to methods for providing styling hold to hair by using an adhesive copolymer or composition of the present invention.
