Abstract
A method of preparing high molecular weight poly(meth)acrylate polymers having narrow polydispersity indices (PDIs) by coupling poly(meth)acrylate building block units which themselves have narrow PDIs. The building block units have halogenated terminations, which when reacted with selected coupling agents, from the high molecular weight poly(meth)acrylate polymers.
