DOCUMENT TYPE: Journal CA Section: 35 (Chemistry of Synthetic High Polymers) Ethylbenzene [100-41-4] and isopropylbenzene [98-82-8] were dehydrogenated to styrene (I) [100-42-5] and a-methylstyrene (II) [98-83-9], resp., on catalysts Ca and Zn borates, mordenite NaM, Ca form of mordenite, and erionite NaKE (III), at 450-550° and O-hydrocarbon mol ratio (0.4-1.1):1. The conversion and selectivity depended on the temp., O-hydrocarbon ratio, and type of the catalyst, being 5-37% and 24-76%, resp., for I, and 6-53% and 27-81%, resp., for II. Best results were obtained with III. .

DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) Compns. having good flame resistance and useful as sheaths for elec. cables contain 100 parts PVC [9002-86-2], 330 parts ethylene-vinyl acetate copolymer (I) [24937-78-8] [vinyl acetate (II) content >15%], 31 Zn compd., and 31 compd. selected from Sb, Mo, Si, Al, Mg, or Ca oxides, hydroxides or carbonates. Thus, PVC 100, I (II content 40%) 50, basic lead sulfate 5, Ba stearate 1, ZnCO3 3, and hydrated alumina 30 parts were blended to give a compn. An insulated elec. cable with a sheath of the prepd.In this experiment, several chemicals are used like 1332-07-6 and 24937-78-8 compn. had burning length 150 cm and burning time 15 min (TEEE-383 burning test). .
