    Abstract: A process for producing moldings containing ester and urethane groups and having a cellular core and a compacted surface zone, preferably shoe soles, comprises reacting a) isocyanate semiprepolymers containing ester groups and having an isocyanate content of from 10 to 26% by weight, which in turn are prepared by reacting ai) 4,4'-MDI or mixtures of 4,4'-MDI and modified or unmodified MDI isomers, with aii) difunctional to trifunctional polyester polyols having molecular weights of from 600 to 3000 and aiii) at least one branched-chain dihydroxy compound containing at least one bonded ester unit as bridge and having a molecular weight of up to 500, with b) at least one relatively high molecular weight polyhydroxyl compound and, if desired, c) low molecular weight chain extenders and/or crosslinkers in the presence of d) blowing agents, e) catalysts and, if desired, f) additives in a closed mold with compaction. The isocyanate semiprepolymers containing ester groups which can be used in this process are liquid at room temperature.

    Abstract: The prodn. of isocyanurate gp.-contg. polyisocyanates (A) comprises partial trimerisation of (cyclo)aliphatic di-isocyanates (B) in the presence of tetra-alkylammonium alkyl carbonates of formula (I) and/or quat. ammonio-alkyl carbonate betaines of formula (II) as catalyst(s), followed by deactivation of the catalyst on reaching the required deg. of trimerisation. In formulae, R , R , R = 1-20 C alkyl, 5-6C cycloalkyl, 7-10C aralkyl or Ph; or R + R can form a 5- or 6-membered cycloalkyl gp., or R + R + N can form a 5- or 6-membered ring with another N or O as bridging gp. or R + R + R + N can form a multi-membered ring with one or more extra N and/or O bridges; R = 1-4C alkyl; R = 2-20 C alkylene, 5-6C cycloalkylene, 7-10C aralkylene or phenylene; or R + R = alkylene gp. which forms a 5- to 7-membered ring with a N bridge. Pref. trimerisation catalysts are carbonates of formula (III), (IV), or (V), or betaine carbonates of formula (V), (VII) or (VIII). Trimerisation is carried out at 30-150 degrees C and the catalyst is deactivated with dibutyl phosphate (DBP); unreacted monomeric di-isocyanate is then removed. Pref. di-isocyanates are (cyclo)aliphatic di-isocyanates obtd. by a phosgene-free process, esp. by thermal cleavage of (cyclo)aliphatic dicarbamate esters; esp. pref. di-isocyanates obtd. by this method are 1,6-hexamethylenedi-isocyanate (HDI), 2-butyl-2-ethyl-pentamethylene-1,5-di-isocyanate and 1-isocyanato-3-isocyanatomethyl-3,5,5-trimethylcyclohexane (IPDI).
