Abstract: 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 DEG C to +30 DEG C. The aqueous solution is prepared by devolatilization 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.

Abstract: An electronically tuned, optically pumped, transition metal based, solid-state laser is disclosed. Tuning is achieved by using resonant reflecting means comprising an output mirror (m3), a mirror (m2) located between the output mirror and the source of laser light, a polarizer (P) located in the light path between the two mirrors, and an electronically tuned, voltage controlled, variable, liquid crystal waveplate (12) for receiving light passing through the polarizer. The components of the resonant reflecting means are selected to have a longitudinal mode that is anti-resonant with the optical cavity of the laser.
