摘要：
A co-grafted polymer dispersion comprising blocks of an organopolysiloxane with OH functional groups, blocks of an ethylene/vinyl ester copolymer containing about 5 to 99% by weight of incorporated vinyl ester, and blocks of vinyl monomer units polymerized in the presence of mixtures of the organopolysiloxane and ethylene/vinyl ester copolymer, the organopolysiloxane and ethylene/vinyl ester copolymer blocks being linked via vinyl polymer bridges. The dispersions mixed with suitable catalysts, can cure under the influence of atmospheric moisture to elastic tack-free rubbers suitable as sealants.
