Poly(methyl methacrylate)s of extremely high molecular weights (>106) and narrow molecular weight distributions (M̄w/M̄n<1.2:1) were easily obtained by living/controlled free-radical polymerization under high hydrostatic pressure (5 kbar; see scheme, AIBN=2,2′-azobis(isobutyronitrile)). This technique provides conditions amenable to industrial scale-up.
