Thiol-polyene system

It should finally be emphasized that the use of DPB is not restricted to acrylic compounds since it proved to be also a very efficient photoinitiator for the polymerization of vinyl monomers, like N-vinylpyrrolidone (NVP). In addition, DPB appeared to be particularly well-suited to photo-cure systems that need hydrogen abstraction type photoinitiators, like the thiol-polyenes resins (2), since it is then to be compared to the poor-performing benzophenone. [Pg.442]

Recently, Starnes and Zaikov have reported that thiol esters such as 2-ethylhexyl 3-mercaptobenzoate function as efhcient stabilizers both by displacement of labile chloride and addition to polyene sequences. In this case, good performance was noted with high-shear dynamic stability testing, using 3 phr of thiol plasticizer/stabilizer. Although it is difficult to visualize such a system being competitive with low-cost tin stabilizers used at levels as low as 0.3 phr, it will, nevertheless, be of interest to follow commercialization of this approach. [Pg.107]
