Abstract: The prodn. of isocyanurate gp.-contg. polyols (I) comprises reacting polyisocyanurates (II) with short-chain, OH gp.-contg. cpds. (III) in presence of carrier polyols (IV) with an OH number of not more than 500 mg KOH/g and a mol. wt. of at least 450. Also claimed are polyols (I) obtd. by this process. Pref. polyols (IV) are based on glycerol and/or trimethylolpropane. The ratio of (III):(IV) = (5-20):1, and the ratio of (III + IV):(II) = (1-5):1. The process comprises heating the mixt. of (III) and (IV) to 190-240 degrees C, adding (II), reducing the temp. by 10-40 degrees C and stirring for 1.5-3 hrs. at this temp. After reaction is complete, the mixt. is either (a) cooled to 50-150 degrees C, treated with not more than 5 wt% alkali or alkaline earth metal hydroxide and stirred for 0.5-1.5 hrs. at this temp. or (b) cooled to 100-160 degrees C, treated with not more than 10 wt% monofunctional glycidyl ether and stirred for 0.5-1.5 hrs. at this temp.

Abstract: Un procedimiento para preparar polioles que contienen grupos isocianurato haciendo reaccionar PIR con compuestos que contienen hidroxilo, de cadena corta. La reaccion del PIR se lleva a cabo en presencia de polioles portadores que tienen un numero OH de cuando mucho 500 mg KOH/g y una masa molecular de cuando menos 450 g/mol. Los polioles que contienen grupos isocianurato preparados mediante este procedimiento pueden utilizarse para producir PUR y PIR.
