## Abstract The spatial degradation in impact PP copolymers with different ethylene contents is studied by FTIR microscopy and layerβbyβlayer milling of the sample surfaces, followed by ATRβFTIR, SEC, and CRYSTAF analysis. FTIR allows for tracking of the rate of degradation, providing information o

## Abstract ICPPs are complex materials that contain various ethylene/propylene copolymers in addition to the majority poly(propylene) phase. To understand their molecular structure, multiple fractionation and analysis techniques are used. In this study, TREF and CRYSTAF are used to study the diffe
TGA curves for the thermal decomposition of PS in nitrogen (dashed line) and air (solid line). Heating rates of 9.0 and 8.2 K N min -1 for nitrogen and air, respectively.
## Abstract The effect of stereoregularity on the thermoβoxidative degradation of poly(propylene)s, isotactic (IPP) and syndiotactic (SPP), was compared with that of high density polyethylene (HDPE) by means of chemiluminescence (CL). SPP is extremely stable to thermal oxidation and CL signals appe
## Abstract Water soluble associative polymers based on polyacrylamide (PAM) grafted with short poly(propylene oxide) (PPO) chains as pendant groups were synthesized. Two different methods were used (1) homogeneous (water +βacetonitrile) (2) micellar copolymerization, in the presence of sodium dode
