Abstract
A possibility to obtain ultra high molecular weight poly(ethylene oxid e) (UHMWPEO) hydrogels by means of swelling samples which has been gam ma irradiated in bulk is presented. A separation of the three fraction s which had been already called macronetwork, micronetworks and sol-fr action promoted by the water influence is observed. The crystalline st ructure after swelling and drying is discussed as well as the cell str ucture of the gels. The effect of the absorbed dose value on the struc ture and properties of the dry products is studied by means of optical and scanning electron microscopy.
