NOVEL BUTENE OLIGOMER DRIVATIVE HAVING FUNCTIONAL gamma- BUTYROLACTONE GROUP

摘要

PROBLEM TO BE SOLVED: To provide a butene oligomer derivative which is a useful macromonomer having a functionalγ-butyrolactone group at the molecular terminal. SOLUTION: This derivative has a hydrocarbon main chain of which at least 80 mol% of the repeating structural units are -CH2C(CH3)2- units. One terminal group of the derivative is tertiary butyl; and at least 60% of the other is a functional group of aγ-butyrolactone type.
