Abstract:
A dual-functional dithiolane diacrylate, (1,2-dithiolane-4,4-diyl)bis(methylene) diacrylate (DT), was designed to integrate intrinsic photoinitiating and crosslinking functions within a single monomer, enabling self-photoinitiated dithiolane-ene copolymerization without external photoinitiators. EPR spectroscopy confirmed the radical mechanism. Copolymerization of DT with acrylamides produced robust UV-cured networks with high optical transparency and strong glass-to-glass, glass-to-polycarbonate, and glass-to-FR4 adhesion.

Olefin Metathesis Polymerization: Acyclic Diene Metathesis (ADMET)
Similar to cross-metathesis, ADMET also involves the formation of metallacyclobutane intermediate by [2+2] cycloaddition of one of the double bonds of a terminal diene with...

Conformation
The simplest example of a diene is 1,3-butadiene, an acyclic conjugated π system. At room temperature, the molecule exists as a mixture of s-cis and s-trans conformers by virtue of rotation around the carbon–carbon single bond. Although the s-trans isomer is more stable, the...
