A new biodegradable PtBA-PHB-PtBA triblock copolymer was successfully synthesized by ATRP method with Br-PHB-Br as macroinitiator,tert-butyl acrylate as monomer and CuBr/PMDETA as the catalyst system.Cleavage of the t...
The degree of ionization of polyacrylic acid and pure sodium polyacrylate solutions covering a wide concentration range was deteremined by measuring the pH values of these solutions.The results show that the degrees o...
