Beschreibung
Zusammenfassung:	The present application provides a process for producing an isocyanate-terminated prepolymer comprising the reaction of a polyisocyanate compound A) with an isocyanate-reactive compound B) and optionally a subsequent step to reduce residual monomer content, wherein- the polyisocyanate compound A) comprises at least 30 wt.-%, based on the weight of the polyisocyanate compound A), penthamethylene diisocyanate, preferably at least 50 wt.-%, more preferably at least 70 wt.-%, and- the isocyanate-reactive compound B) comprises at least 80 wt.-%, based on the weight of isocyanate-reactive compounds B), of(I) poly(1,3-propanediol) with a number average molar mass in the range of from 100 g/mol to 1300 g/mol, or(II) poly(ε-caprolactone) with an OH-functionality of 2 and a number average molar mass in the range of from 160 g/mol to 800 g/mol, or(III) any combination of (I) and (II).
