Abstract

This invention discloses a double-chain polymer, its preparation method, and its applications. The double-chain polymer has the structure shown in formula M. The double-chain polymer of this invention is prepared in a one-step process under mild conditions (e.g., a reaction temperature of 60°C) and without a catalyst, yielding a double-chain polymer with a number-average molecular weight of over 2000. This invention offers a simple preparation method that eliminates the need for catalysis, greatly simplifying the preparation process.
