The kinetics for the coil-to-globule transition of linear poly(N-isopropylmethacrylamide) (PiPMA) chains has been studied by use of the fluorescence and Rayleigh scattering with a fast laser pulse infrared heating. We have observed the two-stage kinetics in the collapse transition with the characteristic relaxation times, τfast and τslow, which are attributed to the nucleation and growth of pearls...
Poly(vinyl chloride) (PVC)/calcium carbonate (CaCO 3 ) nanocomposites were synthesized by in situ polymerization of vinyl chloride (VC) in the presence of CaCO 3 nanoparticles. Their thermal, rheological and mechanical properties were evaluated by dynamic mechanical analysis (DMA), thermogravimetry analysis (TGA), capillary rheometry, tensile and impact fracture tests. The results...
Nano-sized antimony trioxide (Sb 2 O 3 ) particles were modified by in-situ methyl methacrylate (MMA)/Sb 2 O 3 polymerization. Subsequently, these modified nanoparticles were compounded with poly(vinyl chloride) (PVC) to prepare PVC/Sb 2 O 3 nanocomposites. In-situ MMA/Sb 2 O 3 polymerization kinetics shows that nano-Sb 2 O ...
