It exhibits attractive heat resistance, but its mechanical properties are rather poor. Polya… WebJan 1, 2024 · Bis(4-chlorophenyl) sulfone (BCPS, CAS No. 80-07-9) is used as monomer for the production of several groups of polymers like polysulphones and polyethersulphones. Residual amounts of monomer remain in the polymer matrix and might migrate out from the polymer matrix. In the present study, freshwater fish and fish-eating birds were examined. cisco eigrp peer termination received
