Abstract: A description is given of polyisocyanates of the formula I in which R and R' are identical or different and are alkyl groups having 1-4 carbon atoms and n is on average from 1.5 to 5 and also of a process for preparing these polyisocyanates in which a polyamine of the formula II in which R, R', and n are as defined above, is reacted with phosgene. The new polyisocyanates are suitable for producing crosslinked polyurethanes from reaction mixtures with low solvent content and for producing coating compositions or adhesives. Also described are the coating compositions and adhesives, and their use.

Abstract: The invention relates to a method for the intrinsically safe handling of 3- chlorpropyne in the presence of a diluent, which has a boiling point under normal pressure in the range of -50 ~C (223 K) to 200 ~C (473 K). According to the method, the concentration of 3-chloropropyne in the liquid phase and in the gaseous phase is maintained below the concentrations at which deflagrati on occurs, by means of the type and quantity of the diluent, the temperature an d the total pressure of the system. The invention also relates to the use of 3 - chloropropyne produced, stored or transported in this manner for the synthes is of dyes, pharmaceutical and agricultural active ingredients, electroplating auxiliary agents, disinfection agents, steroids and growth hormones.
