Optical, thermal, mechanical, and chemically recyclable properties of polydithiourethane films

Abstract

Optical, thermal, and mechanical properties of aliphatic polydithiourethane (PDTU) films synthesized with diisothiocyanates and dithiols having methylene chains of different carbon numbers as monomers were evaluated, and the effect of methylene chain length on the properties of the resulting polymers was investigated. Furthermore, we compared the physical properties of network PDTU films synthesized with trifunctional isothiocyanates or trifunctional thiols as crosslinkers with those of films molded from chain polymers, and investigated their chemical recycling behavior.
