BLOCK COPOLYMER HYDRIDE AND MANUFACTURING METHOD OF BLOCK COPOLYMER HYDRIDE

摘要

To provide block copolymer hydride capable of molding a molded body high in heat resistance and high in adhesiveness to a molded body consisting of cyclic olefin ring-opening polymer hydride (COP).SOLUTION: There is provided block copolymer hydride [D] by hydrogenation of a block copolymer [C] consisting of at least 2 polymer blocks [A] mainly containing an aromatic vinyl monomer unit derived from an aromatic vinyl compound, and at least one polymer block [B] mainly containing a chain conjugated diene monomer unit derived from a chain conjugated diene compound, an elution curve measured by gel permeation chromatography (GPC) has at least 2 block copolymer hydride derived peaks (A and B in elution order), a ratio of detection sensitivity (mV) of the peak A to detection sensitivity of the peak B is 1.5 to 9.0, and standard polystyrene converted molecular weight based on elution time of the peak B is 5000 or more.SELECTED DRAWING: Figure 1
