The reactions of HF, BF3, or certain organic fluorine compounds with AlCl3, (C2H5)3Al, or ethylaluminum chlorides in chlorinated hydrocarbons give rise to gels which exhibit pronounced stereoregular polymerization initiating ability toward methyl vin

Development of new catalysts allowed the synthesis of more highly stereoregular poly(methyl vinyl ethers) (PMVE). PMVE properties are markedly dependent on the degree of stereoregularity. Infrared is employed to establish an index of stereoregularity
