| 摘要 |
The present invention relates to a stabilizer composition (S), composed of (i) at least one UV absorber solid under standard conditions, selected from the group of the diphenylcyanoacrylates with a molar mass of at least 500 g/mol and (ii) at least one UV absorber which is liquid at 50° C. and standard pressure. The present invention also relates to a polymer composition, comprising this stabilizer composition (S), and to a process for preparation of polyisocyanate polyaddition products via reaction of polyisocyanates with compounds reactive toward isocyanates, where the reaction takes place in the presence of this stabilizer composition (S).
