Abstract
The proposed device for producing polymer articles from monomers is characterized in that the means for preparing the polymer melt is made in the form of at least one chamber of elastic material, the height of which is several times less than its width and length. Said chamber is placed inside a heated housing filled with a medium intended to exert the required pressure on the chamber walls.
Claims10
A device for producing polymer articles from monomers, comprising:
- a source having means to supply a monomer, a mold, a means for preparing a polymer melt out of the monomer having an inlet communicating with said source of the monomer and an outlet communicating with said mold, at least one chamber having walls constructed of a flexible resilient material, said chamber being disposed intermediate said inlet and said outlet and having means communicating therewith, said chamber having a height several times less than its length and width, said chamber being disposed in a housing, said housing confining therein a medium, means to pressurize said medium to thereby exert pressure on the walls of said chamber, and means operable to heat said housing and said medium to thereby heat said chamber and the melt therein.
