This paper presents mainly the kinetic process of the radiation synthesis of PHEMA hydrogel The major results obtained are:,(1) In the kinetic process, at first the HEMA is polymerized by radiation, and then the PHEMA gel is formed after conversion 20%.,(2) The polymerization-crosslinking of HEMA is proceed by the free radical mechanism: Vo∝I,0.6,.,(3) This radiation-crosslinking process only need a small irradiation dose such as less than 1×10,4,Gy, thus a high gel (more than 90%)can be obtained.,(4) The properties of PHEMA hydrogel are as follows:,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42648903&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42648902&type=
