Title:
HYDROGENATED CONJUGATED DIENE GRAFT POLYMER, METHOD FOR PRODUCING SAME, POLYMER COMPOSITION, MOLDED ARTICLE, AND CROSSLINKED PRODUCT
Document Type and Number:
WIPO Patent Application WO/2023/276741
Kind Code:
A1
Abstract:
Provided are a hydrogenated conjugated diene graft polymer having exceptional affinity for polar materials as well as high thermal stability, and a method for producing the hydrogenated conjugated diene graft polymer. The hydrogenated conjugated diene graft polymer includes a main chain (a) composed of a polymer including a conjugated diene unit, and a side chain (b) composed of a polymer including at least one monomer unit selected from the group consisting of conjugated diene units and aromatic vinyl compound units, at least some of the carbon-carbon double bonds included in the conjugated diene units being hydrogenated, wherein the side chain (b) is bonded to an atom included in a monomer unit that forms a branched portion in the main chain (a), and a hydroxyl group is bonded to the main chain (a).
