Polymerization by phase-transfer catalysis 3: Poly(1,4-oxylylene thioethers) synthesis

Poly(1,4-oxylylenethioethers) were synthesized from 2,5-disubstituted-1,4-bis(chloromethyl)-benzenes and sodium sulfide under phase-transfer conditions. The polythioethers were characterized by elemental analysis and infrared spectroscopy. The effect of the catalyst, solvent, and temperature were studied. Their glass transition temperature and thermal decomposition were determined.
