The crystallization kinetics of blends made of poly(p-phenylene sulfide) (PPS), with a liquid crystalline polymer (LCP) was studied. The blends were found to be immiscible by dynamic mechanical thermal analysis (DMTA). Results of non-isothermal and isothermal crystallization experiments made by diff
## Abstract The Raman and infrared spectra of ^13^Cβsubstituted polyβ__p__βphenylene (PPP) and the Raman spectra of Naβdoped PPP excited at 488.0 and 1064 nm were observed and compared with the corresponding spectra for the ordinary (^12^C) polymer. ^13^C substitution is shown to be useful for char
