Embodiment Construction

[0068] The present invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited to the following embodiments.

[0069] Such as figure 1 , figure 2 , image 3 with Figure 4As shown, the photoinitiated solution polymerization experimental instrument provided by the present invention includes a chassis 100, which is made of white iron sheet that has a shielding effect on ultraviolet light, and its inner layer is coated with non-smooth, internally added ultraviolet absorber 2-hydroxyl -The black coating of 4-n-octyloxybenzophenone can absorb a large amount of ultraviolet light irradiated thereon, in order to prevent the impact on the accuracy of experimental data due to the reflection of light; thicker steel is used at the bottom of the cabinet 100, to increase its weight. A sliding support frame I103 is fixed on the bottom of the cabinet 100, which includes a connected slide bar (not shown) and a screw ro...

Abstract

The invention discloses an experimental instrument for photo-initiated solution polymerization. The experimental instrument comprises a cabinet and is characterized in that a plurality of narrow-band ultraviolet lamps and a polymerization reaction vessel are arranged in the cabinet; a sliding bracket I is arranged at the bottom of the cabinet, and the narrow-band ultraviolet lamps are vertically arranged on the sliding bracket I; the polymerization reaction vessel is arranged in the moving direction of the narrow-band ultraviolet lamps, and a gap is formed between the narrow-band ultraviolet lamps and the polymerization reaction vessel; the polymerization reaction vessel can rotate around the axis of the polymerization reaction vessel; sliding brackets II are arranged at the two sides of the polymerization reaction vessel, and slit adjusting devices are arranged on the sliding brackets II and can move along the sliding brackets II; and a light intensity sensor I and a light intensity sensor II are arranged in the moving direction of the narrow-band ultraviolet lamps. According to the experimental instrument, the use and combination number of ultraviolet lamp sources can be controlled in a manner that slit width or shading time is adjusted by slit transmission adjusting devices, and the light radiation energy received by a polymerization system can be adjusted and controlled through adjusting the distance between light sources and a reaction device, so that a method for controlling primary-activity free radical generation rate by using multiple control manners is realized.

Description

technical field [0001] The invention relates to an experimental instrument for photoinitiated solution polymerization, and belongs to the technical field of photopolymerization synthesis of high polymers. Background technique [0002] Water-soluble ultra-high molecular weight polymers (molecular weight greater than 10 7 ) mainly refers to polyacrylamide (PAM) polymers, which are formed by homopolymerization of acrylamide or copolymerization with other monomers. High molecular weight polyacrylamide is mainly used as a flocculant and thickener ("Water-Soluble Polymer") Yan Ruixuan, Chen Zhenxing, etc., Chemical Industry Press, 1988). The synthesis of water-soluble ultra-high molecular weight polymers is a process of free radical polymerization or free radical copolymerization, which can be divided into thermally initiated polymerization and photoinitiated polymerization according to the different energy sources provided. In the process of thermally initiated polymerization, ...
