A process for the preparation of a silylated polymer composition comprising (a) adding at least one at least one phosphite stabilizer and at least one sterically hindered phenol to a polyol before adjustment of the temperature, before reaction with a chain extender and/or before reaction with a silylating agent to provide for a stabilized prepolymer containing reactive functional groups mixture; (b) directing the stabilized prepolymer contain reactive function groups mixture of step (a) to a silylation unit; (c) adding a silylating agent to the stabilized prepolymer containing reactive functional groups mixture in the silylation unit of step (b) to provide for a silylation reaction mixture; (d) reacting a prepolymer containing reactive functional groups with a silylating agent in a silylation reaction mixture of step (c) to provide for an intermediate product comprising a partially silylated polymer; (d.1) directing at least a portion of the intermediate product comprising a partially silylated polymer to a quenching unit; (d.2) adding at least one isocyanato-reactive scavenging agent possessing at least one active hydrogen to the quenching unit containing the intermediate product comprising a partially silylated polymer of step (d.1) to provide for a quenching mixture; (d.3) reacting the least one isocyanato-reactive scavenging agent possessing at least one active hydrogen with the partially silylated polymer present in the quenching reaction mixture of step (d.2) in the quenching unit to produce a silylated polymer composition; and (e) removing the silylated polymer composition from the quenching unit of step (d.3) to produce a silylated polymer composition; 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.
