Modified diene-alpha-olefin copolymer and method for producing same

摘要

A modified diene-alpha-olefin copolymer which is represented by the formula (1) below and has H₂C-C(R⁵)-COO- in at least a part of the ends. wherein R¹ and R² independently represent a hydroxyl group or H₂C-C(R⁵)-COO-, R³s, R⁵s, and R⁶s are independently represent a hydrogen atom or an alkyl group having 1 to 10 carbon atoms, R⁴s independently represent a phenyl group, a pyridyl group, a chlorine atom, a cyclohexyl group, or a carbonyloxyalkyl group, and l, m, and n represent the number of repetition.
