Patent ID: 7067605

Claim:
An organic polymer having an end structure expressed by general formula (1): (wherein R 1 represents an alkyl group having a carbon number in the range of 1 to 20, an aryl group having a carbon number in the range of 6 to 20, an aralkyl group having a carbon number in the range of 7 to 20, or a triorganosiloxy group expressed by (R′) 3 SiO—; R 2 represents an alkyl group having a carbon number in the range of 1 to 20, an aryl group having a carbon number in the range of 6 to 20, an aralkyl group having a carbon number in the range of 7 to 20, an alkoxy group having a carbon number in the range of 1 to 20, or a triorganosiloxy group expressed by (R′) 3 SiO—; if the number of R 1 s or R 2 s is at least two, they may be the same or different; R′ represents a monovalent hydrocarbon group having a carbon number in the range of 1 to 20 and the three R′s may be the same or different; X represents a monovalent organic group having an epoxy group and/or an oxetanyl group, and if the number of Xs is at least two, they may be the same or different; m represents an integer in the range of 0 to 20; and n represents an integer of 1, 2, or 3), and wherein the main chain skeleton of the organic polymer comprises a saturated hydrocarbon polymer selected from the group consisting of polyisobutylene, hydrogenated polyisoprene, hydrogenated polybutadiene, and copolymers thereof.
