A method for producing an adhered or sealed anodized aluminum product or a glass product surface-treated by metal or a metal compound, by using as adhesive or sealant a curable composition, in an adhering treatment or sealing treatment of an adhesion substrate composed of anodized aluminum or glass surface-treated by metal or a metal compound, wherein the curable composition comprising (A) a saturated hydrocarbon polymer having at least one silicon-containing group crosslinkable by forming a siloxane bond and having a hydroxyl group or a hydrolyzable group bonded to the silicon atom, and (B) a silane coupling agent selected from a group comprising an epoxy group-containing silane coupling agent and an isocyanate group-containing silane coupling agent.

Method for adhering or sealing

Process for isolation of isobutylene polymer

A method of preparing a polymer containing functional groups by reacting a polymer (A) having alkenyl groups with less than 1/N mole ratio with respect to the mole number of the alkenyl group of a silicon polyhydride compound (B) having 2 to 6 hydrogen-silicon bonds in one molecule, so as to increase the molecular weight and leaving unreacted alkenyl groups remain in molecules, or if desired, by adding the silane compound (C) in the reaction system so as to react the silane compound with the remaining alkenyl group in one-point process.

Method of preparing polymer containing functional group

An isobutylene base polymer with a functional group having repeating units derived from isobutylene and at least one unit of the formula: ##STR1## wherein R.sup.1 is a hydrogen atom, a methyl group or an ethyl group and R.sup.2 is a divalent organic group, and a number average molecular weight of 500 to 500,000.
