Functional substances derived from oligoolefins having functional groups at the ends

Abstract

An amphiphilic functional substance with lipophilicity, affinity for supercritical CO, and if necessary hydrophilicity comprising an oligoolefin chain and a perfluoroalkyl group(s) at a single end thereof or at both ends thereof with or without the intervention of a poly(oxyalkylene) chain, which enables the utilization of supercritical COas a reaction medium; a photopolymerizable functional substance comprising an oligoolefin chain and a reversible photopolymerization/dissociation group(s) at a single end thereof or at both ends thereof and a functional substance comprising a photo- and/or thermodissociable polymer obtained by photopolymerization of the aforementioned photopolymerizable functional substance, which can be utilized as recycle polymers; a hydrolyzable functional substance comprising a polymer obtained by chain-elongating plural oligoolefin chains through ester linkages, which can be utilized as a recycle polymer; and a functional substance capable of forming a microphase separation structure comprising a polymaleimide comprising an oligoolefin chain and a polydimethylsiloxane chain which are bonded to form an imide linkage, which can be utilized as a functional product such as an electronic material. There is also provided novel oligo(1-butene) containing a terminal vinylidene group, which is useful as a raw material in producing the group of functional substances described above.
