The kinetics of grafting-through polymerization of PDMS11MA macromonomers was studied to establish correlations between reversible first-order kinetic trends and network mechanical properties. By varying the reaction conditions, including the initial monomer concentration, targeted degree of polymerization, and solvent, the syntheses of macroinitiators and chain extensions were optimized with improved chain-end fidelity while maintaining a high yield and provided elastomers with consistent desired mechanical properties.
New thermoresponsive graft copolymers with an aromatic polyester backbone and poly(2-isopropyl-2-oxazoline) (PiPrOx) side chains are synthesized and characterized by NMR and GPC. Their conformational properties in nitropropane as well as thermoresponsiveness in aqueous solutions are studied and compared with that of free side chains, i.e., linear PiPrOx with a hydrophobic terminal group.
