Preparation method of organic tin-free chlorine ether resin

Abstract

The invention provides a preparation method of organic tin-free vinyl chloride-isobutyl vinyl ether copolymer resin (chlorine ether resin for short). The preparation method comprises the steps of adding the materials including deionized water, an emulsifying agent, a buffer agent and the like into polymerizing kettle, heating to a specified temperature, adding an emulsified mixture of the materials including vinyl chloride, isobutyl vinyl ether, deionized water, an emulsifying agent, a buffer agent, stabilizers and the like and materials including an initiator and the like in a batch or continuous manner to generate polymerization, and adding the stabilizers in the later period of the reaction, so as to obtain the organic tin-free chlorine ether resin, wherein the stabilizers are substances containing non-organic tin stabilizers with epoxy groups. The prepared organic tin-free chlorine ether resin has good thermal stability and can be applied to the fields of ink, coatings and the like of tools, foods and medical products. The preparation method has the advantages that the chlorine ether resin does not contain organic tin and has good thermal stability.

AI Technical Summary

Benefits of technology

This patented technology produces an improved type of chemical called chiorooxtanolide (chlorophyll) which contains no harmful metals found on plastic materials used for packages or containers made from them. These chemistries have excellent heat resistance properties but they don't require any other ingredients beyond what was previously mentioned. They work with various types of substances including benzene, naphtha, coal tar, petroleum oil, etc., making their use more convenient compared to previous methods involving tin compounds.

Problems solved by technology

This patented describes different methods for improving the performance of thermosetting compositions made up of chiorate diklyther sulfone monomethaccharide and unsaturation stable organochromium catalysts called dichrome initiators. These techniques aim at increasing the efficiency and quality of these chemically active ingredients while reducing environmental concerns associated therewith.
