4,4'-Dichlorodiphenyl sulfone (DCDPS) is an organic compound with the formula (ClC6H4)2SO2. Classified as a sulfone, this white solid is most commonly used as a precursor to polymers that are rigid and temperature resistant such as PES or Udel.
- ClC6H5 + SO3 → (ClC6H4)2SO2 + H2O
DCDPS is the starting material in the polymerization of compounds such as Udel, PES and Radel R. The polymerization occurs through a nucleophilic substitution reaction of DCDPS with difunctional nucleophiles. With bisphenol A in dimethyl sulfoxide, DCDPS forms a material called Udel. This and related condensations adhere to the following stoichiometry:
- (ClC6H4)2SO2 + HO-X-OH → 1/n [(O-X-OC6H4)2SO2]n + 2 HCl
Udel is a high performance amorphous sulfone polymer that can molded into a variety of different shapes. It is both rigid and temperature resistant, and has applications in everything from plumbing pipes, to printer cartridges, to automobile fuses. DCDPS also reacts with bisphenol S to form PES. Like Udel, PES is a rigid and thermally resistant material with numerous applications.
