Description

  The present invention relates to a diene polymer having excellent heat resistance and a method for producing the same.

  Two compounds represented by the following formula (3) such as 5-allyl-5-((2E) -2-butenyl) -2,2-dimethyl-1,3-dioxane-4,6-dione A polymer obtained by polymerizing a non-conjugated diene compound having a carbon-carbon double bond with a general addition polymerization catalyst is not a diene polymer having an excellent balance between heat resistance and processability. Because one of the two carbon-carbon double bonds is involved in an addition polymerization reaction, the other is involved in an inconvenient reaction such as a crosslinking reaction rather than the addition polymerization reaction. This is because the coalescence does not have a ring structure that contributes to heat resistance in the main chain, and is not necessarily a thermoplastic polymer that contributes to excellent processability.

  Further, an ethylene-cyclopentane alternating copolymer obtained by coordination ring-opening polymerization described in “Macromolecules”, Vol. 35, 2002, pages 9640-9647, Although it has excellent heat resistance due to the presence of a ring structure, (1) synthesis of the monomer having the target substituent is not easy in the synthesis method described (2) in the hydrogenation step which is essential after polymerization The problem of the possibility of reducing the substituent is pointed out.

Therefore, the ratio (mol%) of threoisotactic triad is determined by the ratio of the area of peak (iii) to the total area of peaks (iii) and (iv) [100 (iii) / {(iii) + (iv )}], And the ratio (mol%) of threodicindiotactic triad is the ratio of the area of the peak (iv) to the total area [100 (iv) / {(iii) + (iv)} ].
