PROCEDURES FOR OBTAINING POLYMERS DERIVED FROM VINYL ACETATE AND THEIR USE
Process for obtaining polyvinyl acetate (Mw=10 000-40 000 daltons) and copolymers of Vac-VA with a molar content of monomer units of vinyl alcohol lower than 30%, high purity and innocuous by oral administration and utilization of the same as agglutinating agents and exclusive or fundamental constit...

| description | Process for obtaining polyvinyl acetate (Mw=10 000-40 000 daltons) and copolymers of Vac-VA with a molar content of monomer units of vinyl alcohol lower than 30%, high purity and innocuous by oral administration and utilization of the same as agglutinating agents and exclusive or fundamental constituents of matrices which control the release of active principles in tables and pellets. The PVAc and the copolymers can be transformed into powders and granules as a base with acceptable stability during its shlf life. |
