Abstract: The polymerization of n-hexyl isocyanate(HNCO) was carried out in the presence of a novel single initiator, rare earth tris (2,6-di-tert-butyl-4-methylphenolate) [Ln (OAr)3].The influences of reaction conditions such as the monomer concentration, the polymerization temperature and time, and the types of solvents on the polymerization of HNCO were studied.Polymerizations of phenyl, i-propyl, p-tolyl, n-butyl and n-octyl isocyanates with La(OAr)3 were also examined.

Key words: n-Hexyl isocyanate, Polymerization, Rare earth tris (2,6-di-tert-butyl-4-methylphenolate)
