Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 707-61-9, is researched, Molecular C11H13OP, about Preparation and properties of carbodiimide oligomers, the main research direction is carbodiimide oligomer preparation property; phospholene oxide polymerization catalyst; polycarbodiimide oligomer.HPLC of Formula: 707-61-9.
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.
