在本发明中，并没有使用分子量亲水性聚合物，聚提供通过可以使用具有亲水性表面的模具中浇铸模制式丙烯的方法生产的含硅类共聚物成形品。 硅胶水凝胶软性隐形眼镜也可供选择。 在具有一疏水空腔表面的模腔中，（a）具有与一组（甲基）丙烯酸硅单体，（b）具有乙烯基团，（c）一种交联单体，和含有聚合引发剂（d）的单体的亲水性单体， 以及制造具有亲水性表面的含有机硅的共聚物的成型体的方法。 为了这个目的，所述聚合引发剂是，10小时半衰期温度（T10）为70℃以上，不超过100℃，聚合，一个在35℃来自聚合引发剂的T10低于T10的温度范围内将被包含在所述单体溶液小时或更长时间 将聚合引发剂保持在比单体溶液中所含的聚合引发剂的T10高1小时以上的P2工序。

In the present invention, and without the use of a molecular weight hydrophilic polymer, poly provides a method that a silicon-containing copolymer molded product may be used to mold the polypropylene having a hydrophilic surface can be manufactured by a casting mold manufacturing method. Also it provides a silicone hydrogel soft contact lenses. In the mold cavity having a hydrophobic cavity surface, (a) (meth) acrylic silicon monomer having a group with, (b) a hydrophilic monomer having the vinyl group, (c) a cross-linking monomer, and (d) monomers containing a polymerization initiator, by polymerizing the solution, there is provided a method of manufacturing a silicon-containing copolymer molded article having a hydrophilic surface. For this purpose, the polymerization initiator is, 10-hour half-life temperature (T10) is more than 70 ℃, is not more than 100 ℃, polymerizing, one hour or more in the range of 35 ℃ a temperature below T10 from T10 of the polymerization initiator to be contained in the monomer solution in the sustain process P1, and the monomer solution temperature above the T10 of the polymerization initiator to be contained in the P2 process is carried out by maintaining at least one hour.
