<p><P>PROBLEM TO BE SOLVED: To provide a method for improving a conventional method so that a polymer particle containing an unknown amount of a liquid foaming agent can be used for producing an expanded- or an expandable-polymer particle, further to provide a method for utilizing a demonstration plant designed to produce the expandable polymer particle so that at least one part of a used polymer can be added as a recycling polymer containing also an addition agent in addition to a controllable amount of the liquid foaming agent. <P>SOLUTION: The method for producing the expanded- or expandable-polymer particle from a fused polymer body and a fused recycling polymer body comprises producing at least one part of the recycling polymer body from a polymer particle containing a recycled liquid foaming agent, and a plant related to production of the expanded- or expandable-polymer particle is provided with an apparatus for treating a polymer particle containing the recycled liquid foaming agent. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
