“…Benzodioxole derivatives are widely used as coinitiators in radical polymerizations via UV light through hydrogen donation. − Moreover, it is also well known that the active hydrogen between two alkoxyl groups in cyclic acetals can be abstracted as a radical under photolytic conditions. − Those generated cyclic acetal radicals are rearranged rapidly by β-scission forming the corresponding ester. Therefore, it could be assumed that in the copolymers containing piperonyl derivatives, a cross-linking reaction may be promoted after UV treatment, as shown in Scheme .…”

Novel waterborne pressure-sensitive adhesives (PSAs) with biobased contents up to 71% and UV-light-tunable features have been developed using piperonyl methacrylate (PIPEMA) as a hard monomer. The biobased monomer was synthesized from piperonyl alcohol (derived from black pepper), and its homopolymer was fully characterized. Emulsion polymerization was chosen as a sustainable strategy to copolymerize piperonyl methacrylate together with biobased 2-octyl acrylate to produce high-solid-content latexes for pressure-sensitive adhesive applications. The UV light curing ability of the piperonyl methacrylate moieties in the copolymer backbone yielded PSAs with excellent shear resistance and reasonable adhesive properties (tack and peel).

“…As monomers, they could also be either thermally polymerized using a free radical initiator (e.g., perfluorodibenzoyl peroxide, in the presence of oxygen19) or photochemically polymerized in the presence of cationic PI 6, 18. It has been reported that cyclic acetals could act as a promoter of the photopolymerization of styrene 20–22. The photochemical addition concerned with cyclic acetals in the presence of BP has been also studied 23, 24.…”

The behavior of six cyclic acetals and related compounds in the photoinitiation step of a radical photopolymerization was investigated. As shown by the photopolymerization kinetic data obtained from FTIR spectroscopy, most of them are efficient coinitiators in the presence of benzophenone (BP) with efficiencies close to a reference amine coinitiator (ethyl dimethylaminobenzoate, EDB). Laser flash photolysis and ESR spin trapping technique were used to study the photochemical mechanisms of the production of initiating radicals and explain the differences in reactivity.
