Hydrogels based on fully synthetic polymers like poly(ethylene glycol) (PEG) could be easily modulated in their network properties and can promote important functions of the extracellular matrix (ECM) such as cell adhesiveness and degradability. These synthetic materials are promising for applications in...
Radii of gyration, second and third virial coefficients, and intrinsic viscosities have been determined by light scattering and viscometry for four-arm star polystyrene samples with weight-average molecular weights Mw of 9.1 × 104 to 3.1 × 106 in benzene at 25 °C. They are compared with ty...

In aqueous solution, they showed reversible sol to gel to sol transition behavior while increasing the temperature from 0 degrees C to 40 degrees C. The larger the molecular weight or the stronger the relative hydrophobicity of the hydrophobic PLGA block, the smaller the critical gel concentration...
