    摘要: One-component, moisture curing compositions which exhibit rapid curing, even with exceptionally low levels of catalyst or with no catalyst at all, can be formulated from alkoxysilane-terminated polymers having alkoxysilane groups bonded to an electronegative, free electron-pair-containing heteroatom via a methylene linking group. Polymer blends containing the alkoxysilane-terminated polymers exhibit rapid cure, even at room temperature, and allow the use of nitrogen containing components such as adhesion promoters.

    摘要: Condensation curable systems employ ordinarily highly reactive polymers bearing methylene-linked alkoxysilyl groups. By limiting the amounts of activating compounds during the preparation of such polymers, the reactivity is sharply decreased, yet can be increased by addition of suitable catalysts. As a result, the polymers may be easily processed, yet the moisture curing times may be adjusted readily.
