Title: Production of vinyl ether polymers
IPC: C08F16/12
Filed: 1947-05-19
Abstract: Polyvinyl alkyl ethers are made by polymerizing a vinyl alkyl ether, at a temperature between - 70 DEG  C. and - 30 DEG  C., in the presence of an acid-reacting condensing agent, an organic liquid diluent comprising essentially a hydrogen-containing halogenated alkane having a freezing point below - 30 DEG  C., and optionally under superatmospheric pressure, but preferably in the absence of oxygen.  The mixture may be prepared below - 70 DEG  C. and polymerization started by raising the temperature.  Specified ethers are methyl, ethyl, propyl, isopropyl, butyl and isobutyl vinyl ethers.  Specified halogenated alkanes are methyl, methylene, and ethyl chlorides, chloroform, monochlorodifluoromethane, ethylene dichloride and ethylidene dichloride.  The halogenated alkanes may be mixed with other diluents such as ethane, propane, butane, toluene, m-xylene, methyl, ethyl butyl or butyl methyl ether.  The condensing agent may be tin tetrachloride, boron trifluoride, stannic chloride, aluminium chloride, gallium trichloride, boron fluoride diethyl ether or boron fluoride dibutyl ether.  When the polymerization is complete the catalyst is inactivated, preferably by adding a solution of ammonium, sodium, or potassium hydroxide, or methyl, ethyl or propylamine or methanol or acetone.  The low temperature may be obtained by adding solid carbon dioxide to the reaction mixture, allowing part of the diluent to evaporate, condensing it and recycling it to the reaction vessel or externally cooling the reaction vessel by using liquid ethylene or by employing a combination of these methods.  The polymers may be used for coatings, transparent sheets, and may be extruded or moulded.  The polymers may be mixed with waxes, paraffins and brittle plastic materials. Specifications 378,544 and 500,211 are referred to.
