<p><P>PROBLEM TO BE SOLVED: To enable, in gas phase polymerization of olefine, to suppress generation of agglomerated products to perform stable continuous operation. <P>SOLUTION: There is provided a production method for olefinic polymers and for performing gas phase polymerization reaction of the olefine in the presence of an olefinic polymerization catalyst so that the Vicat softening point Tv (°C) of the produced olefinic polymer and the polymerization reaction temperature Tr (°C) satisfy formula (I): -5≤Tv-Tr≤9. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
