The thermal degradation of poly(o-acetylstyrene) (POAS) was studied at 390Β°C under high vacuum. The principal reactions are removal and decomposition of acetyl groups, depolymerization, random chain scission and oligomer formation. The degradation mechanism resembles that of polystyrene (PS) but the

Dilute solutions (2 x 10 -3 M) of poly(para-propionylstyrene) were exposed to long-wave u.v. radiation (2 ~> 300 rim) under high vacuum at 25Β°C. Methane and ethane were formed, their quantum yields [<10-4mol(einstein) -I] being lower than those observed for the solid state photolysis. Both s-cleavag
Due to their interesting properties, zwitterionic polymers have been extensively studied; however, only a few reports discuss their thermal degradation. The objective of this work was to study the pattern of thermal degradation of three poly-(sulfobetaines) with different lateral chain lengths and t
