    摘要: A crosslinkable silane-terminated polymer is provided which includes the reaction product of an isocyanate-terminated prepolymer and a silane possessing a plurality of hydrolysable sites and at least one active hydrogen-containing group which is reactive for isocyanate, the silane upon hydrolysis produces a reduced amount of volatile organic compound compared to that produced by the hydrolysis of a silane possessing an equivalent number of hydrolyzable sites all of which are hydrolyzable alkoxy groups.
