摘要：The invention proposes use of ammonia water in place of a conventional causticalkali or amine compound as a catalyst in the siloxane rearrangement reaction for thepreparation of a silicone-based pressure- sensitive adhesive between apoly(diorganosiloxane) having a linear molecular structure and another
organopolysiloxane composed mainly of the monofunctional organosiloxane units andtetrafunctional siloxane units. The ammonia water after completion of the reaction can beeasily and completely removed by distillation so that the resultant adhesive product isfree from any alkaline residue of the catalyst to be imparted with greatly improvedstability against viscosity changes and excellent electrical properties along with highreproducibility of the product quality.
