Process for producing polymer films from aqueous polymer compositions |
| abstract |
The present invention relates to a process for producing a polymer film from an aqueous polymer composition wherein the process comprises the steps of: (A) introducing an aqueous composition comprising water and a polymer through at least one feed unit in one or more upstream sections of an extruder comprising a plurality of interconnecting sections wherein at least one downstream section comprises a homogenizer mixer; (B) conveying the composition through the extruder; (C) maintaining the composition at a temperature of from about 60° C. to about 160° C. as it is conveyed through the extruder; (D) reducing the pressure in at least one section of the extruder downstream of the feed units sufficiently to evaporate at least a portion of the water in the composition conveyed through that section; (E) removing the evaporated water from the extruder through at least one vent in a downstream section to form a water-reduced composition; and (F) extruding the water-reduced composition through a die thereby to produce a film. n In other embodiments, the invention relates to a process for producing sheets of a pressure-sensitive adhesive composition and to a process for coating a composition such as a pressure-sensitive adhesive composition onto a support web. In each of the embodiments of the invention, a film, sheet or coating composition is formed from an aqueous composition containing large amounts of water, and the product obtained is essentially water-free. |
