PROCESS FOR THE PREPARATION OF SILYLATED POLYMERS HAVING LOW COLOR AND COLOR STABILITY

摘要

A batch or continuous process for preparing silylated polymers having low color and color stability comprising silylating a prepolymer having reactive functional groups with a silylating agent and optionally quenching the silylated polymer, where a stabilizer package containing at least one phosphite stabilizing agent is used.

主权项

1. A process for the preparation of a silylated polymer comprising
reacting a prepolymer with a silylating agent, by a silylation reaction, to produce a silylated polymer composition; and adding a stabilization package containing a phosphite stabilizer to the process before the silylation reaction, to the silylation reaction or after the silylation reaction; with the proviso that when the process is a continuous process, the process does not include backmixing of at least a portion of the silylated polymer composition.
