| titleOfInvention | Process for the continuous casting of liquid polymerizable compositions |
| abstract | A process and apparatus for the continuous casting of a liquid polymerizable composition comprising feeding the liquid polymerizable composition together with a pair of continuous gaskets into a spacing between a pair of moving endless belts arranged such that the lower run of the upper belt is disposed above the upper run of the lower belt and said runs are driven concurrently in the same direction at substantially the same speed, said gaskets being fed such that they circumscribe both side end portions of the spacing to form a cavity, while moving together with the moving belts and keeping in contact with the opposing surfaces of the belts. Passing the composition through a portion of the path of the belts to partially polymerize said composition to such a viscosity that a common logarithm of its viscosity in terms of poise at the temperature of polymerization is within the range of 2 to 5, then passing a portion of the path thereof arranged so as to be curved at least once to bring its degree of polymerization within the range of 40 to 60 weight per cent, and thereafter passing the composition through a straight portion of the path for complete polymerization, said path for polymerization being arranged such the lower and upper runs of the respective belts are brought closer together to follow shrinkage of the composition upon polymerization. Finally the resultant polymerized plate product with a good preciseness in thickness in the widthwise direction and with favorable surface qualities is removed, from the discharge end of the belts. |
