“…There have been several efforts since the late 1970s to revive the use of thiol-ene photopolymerization in industrial applications, including those of Klemm and coworkers [13][14][15][16][17][18][19][20][21][22] in Germany and early and mid 1990s, Jacobine, Woods, and coworkers [23][24][25][26][27][28][29][30][31][32][33][34][35] in the United States in the early 1990s, and Toh and coworkers [36][37][38][39][40][41][42] in Australia beginning in the mid 1990s. Perhaps the most successful industrial use of thiol-ene photopolymerization since the 1970s era has been by Norland Products, which has successfully marketed photocurable thiolene optical and electronic adhesives for a number of years (the details of their use in technical applications is discussed later).…”

“…Descriptions of the use of thiols in chemical reactions extend well over 100 years, encompassing a number of fields ranging from biochemistry to polymer science. Early work on thiol–ene free‐radical chemistry dates from the late 1930s to the early 1950s 1–23. An excellent review of thiol chemistry was published in 1974 covering all of the work on thiols to the mid 1970s 4.…”

ABSTRACT:The photopolymerization of mixtures of multifunctional thiols and enes is an efficient method for the rapid production of films and thermoset plastics with unprecedented physical and mechanical properties. One of the major obstacles in traditional freeradical photopolymerization is essentially eliminated in thiol-ene polymerizations because the polymerization occurs in air almost as rapidly as in an inert atmosphere. Virtually any type of ene will participate in a free-radical polymerization process with a multifunctional thiol. Hence, it is possible to tailor materials with virtually any combination of properties required for a particular application.

The synthesis of novel telechelic monodispersed diols produced from the radical monoaddition of an excess of 10-undecenol with novel a,cudithiols, initiated by peroxides, is presented. The telechelic dithiols employed were prepared from nonconjugated dienes and a commercially available dithiol, or by esterification of adipic acid with 2-mercaptoethanol. From these dithiols, the diols were selectively obtained in high yields. Such a,wdihydroxylated compounds were characterized by both 'H and l3C NMR spectroscopy. The diol which exhibits the ester functions shows excellent solubility in common organic solvents contrarily to the other ones. The physical properties (Tg, T,,, and decomposition temperatures) of these diols were compared and it is noted that the thermostability of these monodispersed telechelic diols is much better than those of the polydispersed commercially available ones such as poly(ethy1ene glyco1)s or poly(tetramethy1ene glyc0l)s. lo) or undecenic monomers 6* '') to commercially available a,u+dithiols and in every case, the yields were excellent. a) Part 3: cf. ref.*) @ 1993, Hiithig & Wepf Verlag, Base1 CCC 0025-1 16X/93/$05.00 w 0 s PI lhb. 2. 9 3

The synthesis of aromatic telechelic monodisperse diols produced from the radical-initiated addition reation of a two-fold excess of 10-undecen-1-01 and new qwdithiols is presented. The dithiols were prepared by esterification of thioglycolic acid with monodisperse telechelic diols obtained by fractionation of oligo(ethy1ene terephthalate)s and oligo(tetramethy1ene terephthalate)s. In all the cases, the long-chain a,odiols were produced selectively and quantitatively. The diols are soluble in most organic solvents, contrary to classical oligo(ethy1ene terephtha1ate)s and oligo(tetramethy1ene terephtha1ate)s.
