Abstract:
PCT No. PCT/EP94/01946 Sec. 371 Date Jun. 27, 1996 Sec. 102(e) Date Jun. 27, 1996 PCT Filed Jun. 15, 1994 PCT Pub. No. WO95/04104 PCT Pub. Date Feb. 9, 1995In order to produce a substantially biologically degradable polymer foam, a thermoplastic or disaggregated starch or a polymer mixture of thermoplastic or disaggregated starch with at least one biologically degradable hydrophobic polymer is used. In addition, the material is mixed with a biologically degradable fibrous or capsular material capable of binding water by capillary action, said material being at least partially treated or saturated with water before being mixed with the polymer. The polymer/material mixture thus obtained is processed under controlled pressure and temperature so that the water bound by capillarity in the material is released and causes the polymer to foam.
