Abstract: 1. IN A PROCESS FOR THE MANUFACTURE OF RESILIENT COMPOUND FOAMS WHEREIN A REACTION MIXTURE OF (A) PREFOAMED SOFT ELASTIC OLEFIN POLYMER PARTICLES HAVING A PARTICLE SIZE OF FROM ABOUT 5 TO 50 MM. AND (B) 20 TO 100 G., PER LITER OF SAID PREFOAMED PLASTICS PARTICLES, OF A FOAMABLE MIX OF POLYISOCYANATES, POLYOLS, WATER, CATALYST AND, OPTIONALLY, (C) OTHER AUXILIARIES, PLASTICIZERS, FINGICIDES, BACTERICIDES, ING OF STABILIZERS, PLASTICIZERS, FUNGICIDES, BACTERICIDES, FLAME RETARDANTS, DYES AND FILLERS IS FOAMED IN A MOLD HAVING A MOVABLE LID, THE IMPROVEMENT WHICH COMPRISES: (1) COATING WATER ONTO SAID PREFOAMED SOFT ELASTIC OLEFIN POLYMER PARTICLES, SAID PARTICLES HAVING A SMOOTH SURFACE AND BEVELLED OR ROUNDED EDGES AND FURTHER HAVING A BULK DENSITY OF FROM 5 TO 100 G./L.; (2) PLACING THE REMAINING COMPONENTS OF SAID FOAMABLE MIX IN THE MOLD WITH A LAYER OF SAID (3) COVERING SAID REMAINING COMPONENTS OF SAID FOAMABLE MIX IN THE MOLD WITH A LAYER OF SAID PREFOAMED SOFT ELASTIC OLEFIN POLYMER PARTICLES COATED WITH WATER; (4) CLOSING THE MOLD; (5) CAUSING SAID COATED PREFOAMED SOFT ELASTIC OLEFIN POLYMER PARTICLES TO CONTACT SAID REMAINING COMPONENTS OF SAID FOAMABLE MIX BY TURNING SAID MOLD; AND (6) ALLOWING THE REACTION MIXTURE TO FOAM WHEREBY A POLYURETHANE FOAM IS FORMED IN WHICH FROM 200 TO 800 ML. OF THE PREFOAMED SOFT ELASTIC OLEFIN POLYMER PARTICLES PER LITER OF FOAM ARE EMBEDDED IN SAID FOAM.
