<p><P>PROBLEM TO BE SOLVED: To provide a means to solve the quality problem for reuse that although a recovered glass part is reusable in prior art, glass splinters cannot completely removed from the interlayer part, when recovering resins contained in the interlayer from a used laminated glass. <P>SOLUTION: The interlayer recovered from the used laminated glass is dissolved in solvent (I), and the resultant solution is filtrated to obtain a resin solution. Solvent (II) is added to the resin solution to precipitate a resin, which is continuously desolvated and dried using a screw extruder-type device to recover the resin from the used laminated glass. <P>COPYRIGHT: (C)2003,JPO</p> |
