The present invention relates to a method of preparing a hyperbranched polyether ester. According to the present invention, a di-functionality haloalkane and a tri-functionality hydroxyl/carboxyl benzene are used as raw materials, and the hyperbranched polyether ester is synthetized in one pot with an A+Bpolymerization method. The present invention is featured by easily obtained raw materials and simple steps, and the prepared hyperbranched polyether ester contains end groups with high reactive activity, so that various functional groups or polymer chains can be introduced into the hyperbranched polyether ester by a further condensation reaction, ring-opening reaction, etc., and thus a hyperbranched polymer with a diversity of properties and unique functions can be prepared.

Method of preparing hyperbranched polyether ester

The present invention discloses a triazine-containing photocurable resin and a preparation method thereof. The preparation method of the resin comprises the following steps of: (1) Dissolving the hexamethylolmelamine the unsaturated fatty acids and a catalyst in a solvent, keeping a reaction going, separating and extracting the reaction product after the reaction ends, obtaining triazine-containing fatty acid ester; (2) adding 50 wt % hydrogen peroxide, a catalyst and a solvent, namely methylbenzene, into the triazine-containing fatty acid ester prepared in step (1), keeping a reaction going, obtaining triazine-containing fatty acid ester epoxy resin; (3) adding a polymerization inhibitor and a catalyst into acrylic acid, dropping the triazine-containing fatty acid ester epoxy resin prepared in step (2), keeping a reaction going, and obtaining the triazine-containing photocurable resin. The photocurable resin of the present invention contains a rigid triazine and flexible fatty chains at the same time, so the cured object has excellent comprehensive performance and can be used as the photocurable resin in the field of photosensitive macromolecular materials.

A preparation method for molecular recognition sensor by electrodeposition is provided. The preparation method is as following: forming molecularly imprinted polymeric micelles by self-assembly of ionic type photosensitive copolymers; forming a film on the surface of an electrode by electrodepositing the molecularly imprinted polymeric micelles at a constant potential; crosslinking the electrodeposited micellar film via ultraviolet light irradiation; extracting the template molecules from the crosslinked film to obtain electrode modified by the molecularly imprinted polymeric micellar film; and connecting the modified electrode with a sensor device and a computer to construct a molecular recognition sensing system capable of specifically detecting the template molecules.
