    Abstract: The invention described herein generally pertains to a composition that includes a silyl-terminated polymer having silyl groups linked to a polymer backbone via triazole. The silyl-terminated polymer is a reaction product of a functionalized polymer backbone and a functionalized silane. The polymer backbone includes a first functional group, which may be one of an azide or an alkyne. The functionalized silane includes a second functional group may also be one of an azide or an alkyne, but is also different from the first functional group. The functionalized polymer backbone is reacted with the functionalized silane in the presence of a metal catalyst.
