摘要：

Photo-emulsion copolymerizations of vinyl acetate (VAc) and vinyl pivalate (VP) were carried out without initiator at 0-degrees-C, and copolymers giving high molecular weight poly(vinyl alcohol) (PVA) with various tacticities were obtained. The tacticities could be controlled between 22.3-12.8% for the isotactic triad and 27.7-38.3% for the syndiotactic triad by varying feed monomer composition.
