    摘要： Moisture curable compositions including silylated polymers and methods for producing the same are provided. A two component moisture curable system for producing a cured or cross-linked silylated polymer having improved compression set properties is provided. The two component system comprises a first formulation and a second formulation. The first formulation comprises a silylated polymer, water, and filler and the second formulation comprises the silylated polymer, a curing catalyst comprising at least one Brønsted acid, and a moisture scavenger. The final cured formulation may have a compression set, determined by ASTM D395 or ISO 815-1, of less than 100%, and in some examples less than 50% and in some examples less than 15%. This demonstrated improvement in compression set not only allows the silylated polymers to be used in applications where cyclic loads are applied but also enhances product durability.
