The invention relates to a process for the manufacture of a molding comprising the steps of
a) preparing an aqueous solution comprising a water-soluble prepolymer having crosslinkable groups and a further polymer which is devoid of crosslinkable groups,
b) introducing the solution obtained into a mold,
c) triggering the crosslinking, and
d) opening the mold such that the molding can be removed from the mold.
According to the process of the invention moldings such as contact lenses may be manufactured with an improved quality and an improved overall yield.
本发明涉及一种制造成型品的工艺,包括以下步骤:a)制备含有可交联基团的
水溶性预聚物和不含交联基团的进一步聚合物的
水溶液;b)将所得溶液注入模具中;c)触发交联;以及d)打开模具,以便将成型品从模具中取出。根据本发明的工艺,例如可以制造出质量更好、综合收率更高的接触镜等成型品。
