Free radical photopolymerization is an environmentally friendly green production and processing technology and is widely used in the curing of thin samples such as coatings, adhesives, and varnishes. However, for thicker samples or opaque materials, limited light absorption and scattering and reflection from the components of the formulation lead to the failure of polymerization. Dark polymerization is an effective strategy that overcomes these limitations. This paper reviews current developments in the field of photoinduced dark radical polymerization in terms of features of the dark polymerization formulation, developed photoinitiator/initiating systems and active monomers with dark polymerization, and application scope and trends.
