p-Methylstyrene - a new monomer and polymer for industry

p-Methylstyrene - a new monomer and polymer for industry. Kaeding, Warren W.; Young, L.Several substances are used for example 108-88-3 and 622-96-8 which are their cas registry numbers. Brewster; Prapas, A. G. (Mobil Chem. Co., Princeton, NJ 08540, USA). Prepr. Pap. - Am. Chem. Soc., Div. Fuel Chem., 28(2), 158-62 (English) 1983. CODEN: ACFPAI. ISSN: 0569-3772. DOCUMENT TYPE: Journal CA Section: 37 (Plastics Manufacture and Processing) The development of a modified zeolite alkylation catalyst highly selective for the prodn. of p-ethyltoluene [622-96-8] made in possible to prep. p-methylstyrene [622-97-9] efficiently. Poly(p-methylstyrene) [24936-41-2] prepd. from the monomer has several advantages over polystyrene, e.g., lower d., higher glass transition temp., decreased molding time, and a potential for radiation-induced crosslinking. .

p-Methylstyrene: a new commercial monomer for the styrenics industry

p-Methylstyrene: a new commercial monomer for the styrenics industry. Kaeding, Warren W.; Barile, George C. (Mobil Chem. Co.Chemicals with cas numbers 24936-41-2 and 25550-14-5 also play role., Edison, NJ 08818, USA). Polym. Sci. Technol. (Plenum), 25(New Monomers Polym.), 223-41 (English) 1984. CODEN: POSTB5. ISSN: 0093-6286. DOCUMENT TYPE: Journal CA Section: 35 (Chemistry of Synthetic High Polymers) PhMe [108-88-3] was alkylated with C2H4 [74-85-1] using ZSM 5 zeolite catalysts having SiO2/Al mole ratio >12 to give EtPhMe [25550-14-5], which was subsequently dehydrogenated to give a mixt. of 97% p-methylstyrene (I) [622-97-9] and 3% meta isomer. The applications of I in the manuf. of homopolymers and copolymers were discussed. The toxicol. of I and its polymers was similar to that of styrene and polystyrene analogs. .
