Problems solved by technology

However, the inherent structural properties of phthalocyanine molecules determine that it is difficult to dissolve, disperse, and process
The traditional method is to mix phthalocyanine into polymer materials, but the dispersion problem is difficult to be fundamentally solved; another method is to turn phthalocyanine molecules into polymerizable monomers, but this transformation is more difficult chemically , high cost, easy to affect the key polymerization reaction, poor adaptability and diversity
So how to polymerize phthalocyanine dyes is an unsolved problem

Embodiment Construction

[0020] Below in conjunction with embodiment the present invention is described in further detail.

[0021] Preparation of functional initiators:

[0022] Tetracarboxyphthalocyanine cobalt and tetracarboxyphthalocyanine iron are used as two starting materials. They have exactly the same method and steps in the process of synthesizing functional initiators, so they are described in a parallel manner. About these two compounds There is a ready-made method for the preparation of , which will not be repeated here. The following are the specific preparation steps:

[0023] 1) Dissolve tetracarboxyl phthalocyanine cobalt (or iron) dye in dimethyl sulfoxide, then add butanediamine, the molar ratio of dye to butanediamine is 1:6, and the weight ratio of dye to dimethylsulfoxide is controlled In the range of 1:4 to 1:5, the temperature of the reaction solution is controlled in the range of 120 to 140°C under stirring, and the reaction time is 3 to 4 hours. Washed several times, filter...

Abstract

The invention relates to a polymerization method of phthalocyanine. An amphipathic compound containing cobalt phthalocyanine (or iron) functional groups and a tertiary amine structure is synthesized and can be used as an initiator for polymerization of free radicals, tertiary amine of the amphipathic compound and potassium peroxodisulfate are subjected to a redox reaction under normal temperature,active free radicals are generated repeatedly, both polymerization of oil-soluble monomers methyl methacrylate and polymerization of water-soluble monomers N-dimethylacrylamide can be triggered on awater / oil interface, thus, the purpose of polymerization of the phthalocyanine is achieved, by the adoption of the mode, functionalization and the polymerization reaction do not interfere with each other, the operation freedom degree is large, the number of the varieties of products is large, polymerization reaction conditions are mild, no organic solvent or emulsifier is used, and the requirements of green chemistry are met.

Description

technical field [0001] The present invention relates to the technical field of synthesis of functional polymer materials, in particular to a polymerized preparation technology of phthalocyanine dyes. Through the new synthesis technology, phthalocyanine dye molecules can be introduced into polyolefin polymer materials to produce a New class of functional polymer materials and their related application technologies. Background technique [0002] Polyolefin is a very important general-purpose polymer material. It is formed by free radical polymerization of several olefin monomers. For different purposes, the structure can be adjusted according to the monomer copolymerization technology, so it is widely used. Initiators are essential in the preparation of polymer materials. The usual initiators are a class of compounds that can generate free radicals, such as oil-soluble peroxygen, azo initiators, and water-soluble persulfates. The use of an initiator must be coordinated with t...
