Abstract
Dendritic poly(esterβamine) with a peripheral hydroxyl [PEA(OH)] was synthesized from dendritic PEA terminated with acrylic double bonds [PEA(ο£Ύ)] and diethanolamine (DEA) by a Michael addition reaction. The effects of the reaction temperature, time, and solvent on the purities of PEA(OH) were studied. It was found that when the mole ratio of PEA(ο£Ύ) to DEA was 1:8 and the reaction was carried out in methanol at 25Β°C for 22 h, the purity of PEA(OH) was 94.6%. The structure of PEA(OH) was identified by IR, ^1^HβNMR, and elemental analysis. PEA(OH) is a surfactant and its aqueous form exhibits cloud points between the mass concentrations of 0.1 and 50 mass %. Β© 2005 Wiley Periodicals, Inc. J Appl Polym Sci 97: 60β64, 2005

## Abstract Novel biodegradable aliphatic poly(esterβurethane)s (PEUs) based on polycaprolactone diol (PCL) and methoxypolyethyleneglycol grafted onto trimethylol propane (mPEGβ__g__βTMP) were synthesized by solution polymerization technique and characterized using a variety of techniques. Microsph
The graft copolymer hydroxyl-terminated polybutadiene-g-polyvinyl ferrocene (HTPB-g-PVF) was synthesized free radically from HTPB and vinyl ferrocene (VF) in benzene, using azobisisobutyronitrile as the radical initiator at 75Β°. The graft copolymer was analysed for its structural and thermal charact
