WebOct 11, 2024 · In an oxyanionic polymerization, glycidol as a latent AB 2 monomer is copolymerized with the protected linear AB glycidyl ether monomer EEGE (ethoxy ethyl glycidyl ether) to generate hyperbranched polyglycerols with an adjustable degree of branching (DB) after deprotection. The DB for the random copolymers is controlled by the … WebEarlier work on the hydrolysis of aryl phosphinothioate esters has led to contradictory mechanistic conclusions. To resolve this mechanistic ambiguity, we have measured linear free energy relationships (βnuc and βlg) and kinetic isotope effects for the reactions of oxyanions with aryl dimethylphosphinothioates.
