Random copolymers of C- with N-substituted glycines (PiPo) were synthesized by carrying out a statistical copolymerization of N-phenyloxycarbonyl-C-substituted glycine (NPC) monomers with N-phenyloxycarbonyl-N-substituted glycine (NNPC) monomers. The copolymerization kinetics were analyzed in detail. The solubility of PiPo was found to highly depend on the compositions of the peptide and peptoid repeat units. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0Safety of Diphenyl carbonate).
Diphenyl carbonate (cas: 102-09-0) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.
