Claim:
1. An acrylic polymer comprising: at least one acrylic block copolymer including a first reactive segment of controlled molecular weight and position that includes at least one monomer having a functional group selected from the group consisting of a self reactive functional group, a reactive functional group, and combinations thereof; and a second reactive segment of controlled molecular weight and position that includes at least one monomer having a reactive functional group, wherein the first reactive segment and the second reactive segments are positioned adjacent to the polymer chain ends, wherein the reactive functional groups are spaced apart along the length of the polymer chain or the reactive functional groups are positioned only in the second reactive segment, and wherein the functional groups of the first reactive segment and the second segment are capable of undergoing crosslinking reactions while remaining reactive with each other, wherein the first reactive segment and the second reactive segment are molecularly miscible before cure as expressed by their properties in the bulk state that are indicative of a single phase behavior, and wherein the self reactive functional a group is selected from the group consisting of silanes, anhydrides, epoxies, alkoxymethylol, and cyclic ethers.
