摘要:
A transparent, non elastomeric, high refractive index, impact resistant poly(thio)urethane/urea material comprising the reaction product of: a) at least one (α, ω)-diiso(thio)cyanate cycloaliphatic or aromatic polysulfide prepolymer, and b) at least one aromatic primary diamine, in an equivalent molar ratio amine function/iso(thio)cyanate function ranging from 0.5 to 2, wherein, said prepolymer and diamine are free from disulfide (—S—S—) linkage and wherein the (α, ω)-diiso(thio)cyanate polysulfide prepolymer is the reaction product of at least one cycloaliphatic or aromatic diiso(thio)cyanate and at least one (α, ω)-diol prepolymer.
