SOLID GRANULAR POLYMER CAPABLE OF BEING FLUIDIZED

摘要

The present invention is directed to a solid flowable particulate polymer having a nominal flow rate of at least 0.6 gram per second through a 1.1 centimeter diameter pipe 7.6 centimeter long under applied pressure of 10.34 MPa. The polymer is capable of producing a substantially uniform predetermined pressure on the surface of an article to be molded in an essentially enclosed pressure vessel in response to heat and/or pressure.
