Abstract

A találmány tárgya eljárás aromás monomer vagy polimer izocianátokelőállítására R1 (NHCOOR2)x általános képletű aromás monomer vagypolimer karbamátok -, a képletben x értéke legalább 1, R1 vagy xvegyértékű aromás csoportot jelent, és R2 egy vegyértékű szervescsoportot jelent - R1(NCO)x általános képletében monomer vagy polimerizocianátok és R2OH általános képletű alkoholok képződéséhez vezetőhőbontásával. A találmány szerint olyan vegyületekből indulnak ki,amelyekben az R2 csoport legalább egy halogén szubsztituenst hordoz. ÓThe subject of the invention is a process for the production of aromatic monomeric or polymeric isocyanates aromatic monomeric or polymeric carbamates of the general formula R1 (NHCOOR2)x -, in the formula the value of x is at least 1, R1 or an xvalent aromatic group, and R2 is a monovalent organic group - in the general formula R1(NCO)x for the formation of monomer or polymer isocyanates and alcohols with the general formula R2OH by thermal decomposition. According to the invention, they start from compounds in which the R2 group carries at least one halogen substituent. HE
