A method for the production of elastic, a compact or cellular the form of bodies on the basis of n - benzyl urea groups containing bonded elastomer, such elastomeric and, in this case, for suitable n - benzyl - polyoxyalkylene - polyamines

摘要

items of the invention are a process for the production of elastic,compact or zelligen formku00f6rpern on the basis of n - containing elastomers through the implementation of benzylharnstoffgruppen committed $(a) at least one organic and / or modified organic polyisocyanat with $a (b) n - benzyl - polyoxyalkylen - polyaminen or mixtures of n - benzyl - polyo xyalkylen - polyaminen and polyoxyalkylen - polyaminen with 2 to 4 of primary amine groups, and (c) minimum $aens a alkylsubstituierten aromatic polyamin with molecular weights up to $500 a in the presence or absence of $a $a and, if necessary, (d) catalysts $e) propellant.$a (f) tools and / or $a $a and g) additives for usable n - benzyl - polyoxyalkylen - polyamines and mixtures of n - benzyl - polyoxyalkylen - polyaminen and polyoxyalkylen - polyaminen with 2 to 4 of primary amine groups, and the elastomers.
