ABSTRACT:
An ultra-high molecular weight methacryloyloxybenzoic acid polymer is provided which, unlike the lower molecular weight polymers of the prior art, is stable even when undergoing melt processing. The method of producing such a polymer involves a free radical polymerization of the monomer at relatively low temperatures in an aqueous solution which contains an alkali metal hydroxide and a free radical initiator.
