POLYOLEFIN HAVING POLYMER CHAIN RESPONSIVE TO STIMULUS

摘要

A block or graft polymer comprising a polymer chain responsive to stimuli and a polyolefin chain directly bonded thereto by chemical bonding is provided as a material which has a polymer chain responsive to stimuli and combines excellent properties of polyolefins with the excellent processability of polyolefins. The polymer is a block or graft copolymer composed of a polyolefin chain and a stimulus-responsive polymer chain whose affinity for a liquid changes upon reception of a stimulus, and is characterized in that the polyolefin chain has been chemically bonded to the stimulus-responsive polymer chain.
