Summary
N methacryloyl-S-methyl-L-cysteine (SMC) homopolymer along with a copolymer with methacrylic acid were prepared in the purpose of studying their complexation with Pd(II). The circular dichroism study showed that the binding of SMC residue to a polymeric chain does not change the coordination donor set of Pd complexation, i.e. ¦N, s ¦. The number of side chains per metal ion involved in the complexation depends on the molar fraction of SMC in the case of the copolymer and on the SMC/Pd ratio for both homopolymer anc copolymer. The variation of viscosity when adding Pd(II) suggests the formation of intramolecular loops.
