Polymers, particularly those used in pressure-sensitive adhesives, are prepared from a mixture of structural isomers of a secondary alkyl (meth)acrylate monomer. The mixture is made by dehydrating a C2-C22 alcohol using a continuous process to form a mixture of olefins, and reacting (meth)acrylic acid with at least some of the mixture of olefins in the presence of an acid catalyst. The adhesives are characterized by exhibiting an overall balance of adhesive and cohesive characteristics.
A reshapable hair styling composition comprising, optionally in a cosmetically acceptable vehicle, at least one (meth)acrylic copolymer, wherein the at least one (meth)acrylic copolymer comprises: (a) units derived from at least one monomer chosen from butyl (meth)acrylate monomers, (b) units derived from at least one monomer chosen from hydroxy alkyl (meth)acrylate monomers, and (c) optional units derived from at least one co-polymerizable monomer other than said (a) and (b) monomers, wherein said composition provides a reshapable effect and is a non-rinse composition.
