Abstract

Abstract:

4,4'-Thiodibenzenethiolhexanediol diacrylate(TBHDA) was synthesized via the "thiol-ene" reaction between 4,4'-thiodibenzenethiol and 1,6-hexanediol diacrylate. For comparison, the thiophenol modified di-trimethylolpropane tetraacrylate(TP-DiTMP4A) and hyperbranched acrylate(TP-P1000A) were also synthesized. The molecular structures of the oilgomers were characterized with ¹H NMR and FTIR spectroscopies. The self-initiated photopolymerization behavior was investigated by photo-DSC measurements. The results show that TBHDA possesses the best self-initiated photopolymerization performance, indicating that the thioether linkage and acrylate double bond concentration both play key role in the self-initiated photopolymerization.

Key words: Acrylate oligomer, Self-initiated photopolymerization, Thiol-ene reaction, Polymerization behavior
