Safety of 4-Methyl-1-phenyl-2,3-dihydro-1H-phosphole 1-oxide. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: 4-Methyl-1-phenyl-2,3-dihydro-1H-phosphole 1-oxide, is researched, Molecular C11H13OP, CAS is 707-61-9, about Preparation and properties of carbodiimide oligomers. Author is Alberino, L. M.; Farrissey, W. J.; Sayigh, A. A. R..
Polycarbodiimides of limited mol. weight were prepared by reacting a difunctional isocyanate, e.g. 4,4′-diisocyanatodiphenylmethane, with a monofunctional isocyanate, e.g. phenyl isocyanate, as terminating agent in the presence of 1-phenyl-3-methyl-2-phospholene-1-oxide [707-61-9] catalyst to give a carbodiimide oligomer [33970-08-0] and CO2. The polymer chains were terminated with end-groups which were equal in thermal stability to the backbone of the polymer. The polymers prepared in the oligomer range having a ratio of equivalents of difunctional to monofunctional isocyanate (r) of 6/1 to 20/1 had mech. properties very nearly equal to those of high mol. weight unterminated polymers. The terminated polymers had a lower melt viscosity than the unterminated polymers and hence a greater ease of processing.
