Embodiments relate to a polymerizable composition comprising a phosphorus-based mold releasing agent for an optical use whose preparation process is improved, and a process for preparing the phosphorus-based mold releasing agent. The phosphorus-based mold releasing agents can be prepared more easily and conveniently by using phosphorous pentoxide, which can easily react with a monoalcohol and/or water at room temperature in the absence of a catalyst or a solvent. In addition, byproducts are not generated during the reaction. Thus, when a lens is produced by using the mold release agent obtained therefrom, it is possible to prevent a defective appearance of the lens that may be caused by byproducts, thereby further enhancing the appearance properties thereof. Further, since separate steps for removing byproducts, specifically, such steps as washing and filtration, are not required, wastewater is not generated. Thus, it is not only environmentally friendly, but the production cost can also be reduced as the process is simple.
本实施例涉及一种用于光学用途的含
磷脱模剂的可聚合组合物,其制备过程得到改进,以及制备含
磷脱模剂的过程。通过使用五氧化二
磷,可以更容易、更方便地制备含
磷脱模剂,五氧化二
磷可以在室温下在无催化剂或溶剂的情况下与单醇和/或
水轻松反应。此外,在反应过程中不会产生副产物。因此,当使用从脱模剂中获得的模具制造透镜时,可以防止由副产物引起的透镜缺陷外观,从而进一步提高其外观性能。此外,由于不需要除去副产物的单独步骤,例如洗涤和过滤等步骤,因此不会产生废
水。因此,它不仅环保,而且由于该过程简单,生产成本也可以降低。
