Abstract

The present invention relates to a selective process for producing polyurethane prepolymers, to the polyurethane prepolymers obtainable from this process, and also to a process for producing moisture-crosslinking silylated polymers, more particularly silane-functional hybrid polymers, and also to the use thereof in CASE sectors (coatings, adhesives, sealants and elastomers).
