PROCESS FOR SIZE-REDUCING SOLID ORGANIC POLYMERS

摘要

A PROCESS FOR SIZE-REDUCING SOLID ORGANIC POLYMERS For recycling, solid organic polymers can be size-reduced between rollers which rotate in the same direction or in opposite directions with a predetermined speed ratio or predetermined shear rate ratio in the roller gap. A shear rate of from 0.0001 sec-1 to 100,000 sec-1 is maintained in the gap. The polymers used have a minimum density of 0.5 kg/m3. Mo3829 Le A 28 848-US/CA
