This paper deals with the preparation and polymerization of various fluroine-containing vinylesters under different polymerization temperatures．By measuring the X-ray diffraction pattern of polyvinyl esters and the IR absorbance ratio D915／D850 of polyvinyl alcohol(PVA) derived from its correspondent polyvinyl esters，no distinct dif-ferences in stereoregularity were obsorved among these polyvinyl esters with different length of polar side groups．But the absorbanee ratio D916／D850 inareaaed．i．e．the stereo-regularity of PVA was enhanced with increasing the length of the polar alkyl side groups of its Predecessors．The stereo and polar effect are obvious．Tho temperature dependanee of tactieity was studied in the range of一78 t0 60℃ and it was found that with lowering of polymerization temperature．there is little affeet on the tacticity of polyvinyl esters．Difference in chain regularity do exist in various fluorine containing polyvinyl esters

these are due to lateral interehain order between ester groups and axe not indicativo of the configuration of the carbon chains．
