Shaped polymeric articles made by two-stage photopolymerization

摘要

A photocureable article which is of simple shape and is capable of being further shaped is formed by partially polymerizing a composition comprising photopolymerizable liquid in the presence of a photosensitive catalyst and then protecting the article from further irradiation. The article may be fibre-reinforced. The article may be subsequently shaped and further cured to produce a rigid article.
