Poly(p-phenylenebenzobisoxazole) (PBO) fiber with polyphenylene sulfide (PPS) pendent groups was made to improve PBO fiber compressive strength by crosslinking. PPS moieties allowed the polymeric network to crosslink at heat-treatment temperatures at

d, l-Glaucine 1.5 H3PO4, is a non-narcotic antitussive for which a sample of carbon-13 labelled material was required for metabolism studies in humans. The sample of 99% enriched d, l-6a-13C-glaucine 1.5 H3PO4 was prepared in 7 steps in 36% overall y

It is shown that the 13C NMR spectral collapse temperatures Tc reported by Axelson and Mandelkern tend to give a constant ratio of Tc/Tg averaging 1.21 ± 0.05 and independent of Tg or of polymer structure. It is further shown that Tc is not a high-f
