Methyl amino ethanol was reacted with PHBHHx to prepare a dihydroxy terminated polyester. The hydroxyl ends of the obtained PHBHHx derivatives were capped with 4,4'-azobis cyanopentanoic acid to obtain the PHBHHx macroazo initiator (PHBHHx-AI) for free radical copolymerization of DMAEMA at 70(o)C. A steady increase in DMAEMA units in the synthesized block copolymer as a function of time was observed. The overall rate constants for the free radical polymerization of DMAEMA initiated by PHBHHx-AI was k = 2.33 x 10(- 4) Lmol(-1)s(-1). Block copolymers were characterized using the (1) H NMR, FTIR, DSC and TGA techniques.eninfo:eu-repo/semantics/closedAccessPoly(3-Hydroxybutyrate-Co-3-Hydroxyhexanoate)Macroazo InitiatorDimethyl Amino Ethyl MethacrylatePolymerization KineticsArticle318Q1Q136883699WOS:000983769600002
