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

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 phosphit...
