    Process for producing vinyl compound polymer
    [10] The present invention relates to a process for the preparation of polymers of vinyl compounds having bulky substituents.
    [11] In the field of polymerization of olefins such as polyethylene and polypropylene, advances in the production of polymers having properties different from those of conventional polymers can be achieved by the introduction of single-site catalysts such as metallocene or non-metallocene catalysts. Has been made.
    [12] Regarding the polymerization of vinyl compounds having bulky substituents such as vinylcyclohexane and the like, the application of such catalysts has been proposed and described, for example, in Polymer Science USSR, Vol. 32, no. 9, 1868-1872 (1990) and Polymer, Vol. 134 (9), 1941 (1993) describe the preparation of copolymers of ethylene and vinylcyclohexane.
    [13] Polymers of vinyl compounds with such bulky substituents exhibit properties similar to polyvinyl chloride and are expected as non-chlorinated materials. However, the known processes for preparing the polymers described above have low copolymerizability of vinyl compounds with bulky substituents (i.e., as compared to the ratio of vinyl compounds with bulky substituents in the monomers provided for polymerization, to the polymers obtained. The ratio of repeating units derived from the vinyl compound is rather low). Therefore, it is difficult to efficiently obtain a copolymer having a high ratio of repeating units derived from a vinyl compound having a bulky substituent, and also to obtain a homopolymer of a vinyl compound having a bulky substituent.
    [14] Summary of the Invention
    [15] It is an object of the present invention to provide a method for producing homopolymers of vinyl compounds having bulky substituents efficiently or for producing copolymers with copolymers containing repeating units derived from vinyl compounds having bulky substituents.
