The (mostly patent) literature was reviewed, covering synthesis, physico-chemical properties and applications of propyltrialkoxysilanes containing the isocyanate group. The silanes are used as coupling agents and also as starting materials to prepare new coupling and crosslinking agents. Several syntheses were described. A method for making isocyanatopropyltrimethoxysilane from 3-chloropropyltrimethoxysilane and alkali metal cyanates, developed by the Team of the A. Mickiewicz University's Faculty of Chemistry and the Poznań Science and Technology Park of the University Foundation, is being industrially applied at the UNISIL Co., Ltd., Tarnow, Poland.

Keywords: isocyanatopropyltrialkoxysilanes, coupling agents, crosslinking agents, syntheses, applications
