| Popis: | New biodegradable block copolymer networks were synthesized from methacrylate-terminated poly(L-lactide) (mLA) and polycaprolactone (mCL) macromers. This allowed the realization of a series of materials in which the macromer ratio can be used to tailor the physical and mechanical properties of the materials. The synthesis of the macromers was characterized using Fourier transform infrared (FTIR) spectroscopy and 1H NMR spectroscopy. Poly(mCL) and poly(mLA) networks were prepared by photopolymerization of the macromers, and copolymers were also prepared from the two macromers in various proportions. The phase microstructure of the new systems and the network architecture were investigated using differential scanning calorimetry, FTIR spectroscopy, dynamic mechanical analysis and thermogravimetry studies. Ideal structure, compatible with the experiments results, for biodegradable poly(L-lactide) and polycaprolactone block copolymer networks. Copyright © 2010 Society of Chemical Industry.
