- METHOD FOR PRODUCING OLEFIN MULTIMER
-
PROBLEM TO BE SOLVED: To solve the problem in which: the amount of by-products of polyolefin tends to increase when the reaction temperature is increased in the case where the olefin multimerization reaction is caused to occur in the presence of a catalyst including a chromium compound. SOLUTION: In a specific reaction temperature range, in the presence of a catalyst for olefin multimerization including a chromium compound (A), a specific compound (B), and a compound such as an organic metal compound (C), the olefin multimerization reaction is caused to occur at a relatively high temperature, so that olefin multimers can be produced while reducing by-products of olefin polymers.
