Abstract
The method comprises the step of putting said streams contg. isocyanate(s) in contact with a soln. of at least one compd. selected from RCH2X(CH2R')CH2(CH2)nFg and R''CH2YCH2(CH2)nFg (R,R',R'' = H, C1-10 hydrocarbyl group optionally contg. heteroatoms; X = N, P, hydrocarbyl contg. N, P; Y = O, S, hydrocarbyl contg. O, S; Fg = primary or secondary amines, OH, SH, preferably Fg is selected from -NH2 and -NHR1, wherein R1 is C1-6 alkyl group having; n = 1-5, preferably 1-2).File in questo prodotto:
