Embodiment Construction

[0019] Below in conjunction with embodiment the present invention is described in further detail.

[0020] Preparation of functional initiators:

[0021] Reactive Brilliant Red K-2BP is used as the starting material. This material has been commercialized, so its preparation has a ready-made method, which will not be repeated here. The following are the specific preparation steps:

[0022] 1) Dissolve 0.1mol reactive brilliant red K-2BP in 400ml water, gradually add 0.3mol NaOH under stirring, then add 0.1mol ethylenediamine, control the temperature of the reaction solution at 40-45°C, and the reaction time at 3-4 After the reaction was completed, most of the moisture was evaporated with a rotary evaporator;

[0023] 2) Add 200 ml of absolute ethanol to the residue obtained in the previous step reaction, add 0.2 mol of isooctyl glycidyl ether under stirring, and continue stirring for 4 to 5 hours at a temperature in the range of 55 to 60 ° C to obtain a purple-red uniform The...

Abstract

The invention relates to a polymerization method of reactive brilliant red K-2BP dye. Synthesize an amphiphilic compound containing a reactive brilliant red group and a tertiary amine structure, which can be used as an initiator for free radical polymerization. Based on the water / oil interface, it can initiate the polymerization of the oil-soluble monomer butyl acrylate and the water-soluble monomer dimethyl diallyl ammonium chloride, so as to realize the reactive brilliant red K‑2BP dye polymer For the purpose of chemicalization, this mode can make functionalization and polymerization do not interfere with each other, has a large degree of freedom of operation, a variety of products, mild polymerization conditions, no organic solvents and emulsifiers, and meets the requirements of green chemistry.

Description

technical field [0001] The invention relates to the technical field of synthesis of functional polymer materials, in particular to a polymerized preparation technology of reactive brilliant red dye, through which reactive brilliant red dye molecules can be introduced into polyolefin polymer materials, thereby Generate a new class of functional polymer materials and 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 the specific poly...
