摘要： What is described herein is a cationic polymerization process for the production of methyl vinyl ether homopolymers which have a relatively high molecular weight and a rather narrow molecular weight distribution. Polymerization is carried out under pressure of an added inert gas so the methyl vinyl ether vapor is effectively absorbed into the liquid phase during the polymerization.

摘要： A process for polymerizing vinyl chloride alone or a mixture of vinyl chloride and other vinyl monomer(s) with hydroxy containing monomer(s), and the copolymer obtained thereby. The hydroxy containing monomer(s) is obtained by the partial allylation of dihydroxy or polyhydroxy alcohols. The copolymers are prepared by suspension polymerization. The presence of the hydroxyl groups significantly modifies the characteristics of the polymers. Plasticizer-take-up is increased and dry-time is reduced significantly. Furthermore, the hydroxyl groups become the sites for postpolymerization reactions due to their polarity and reactivity.

摘要： A process is disclosed for the preparation of liquid and aqueous solutions of amorphous colorless poly (vinyl methyl ether) polymer with low level of impurities from purified vinyl methyl ether. The polymer has relatively high molecular weight, narrow molecular weight distribution and does not degrade readily due to the presence of impurities. The purification of the monomer uses a procedure selected from the group consisting of a vapor-liquid separation, a solid-liquid separation and combinations thereof to remove the impurities at a temperature within the range of from -20.degree. C. to +30.degree. C. The aqueous solution is prepared by devolitilization of solvent solutions of the polymerized purified vinyl methyl ether monomer. The solid polymer is prepared by heating the aqueous solution of the poly(vinyl methyl ether). The amorphous polymers of poly(vinyl methyl ether) are particularly suited for adhesive applications.
