The object of the present invention is to provide a method for producing a (meth)acryloyl-terminated polyisobutylene polymer in which the auxiliary material used in the manufacture is easily removed, the burden of purification step and waste amount are decreased, and the transparency of the polymer is excellent. The method for producing the (meth)acryloyl-terminated polyisobutylene polymer contains a step 1 of polymerizing an isobutylene monomer under the presence of a Lewis acid catalyst to prepare a halogen-terminated polyisobutylene polymer (B), a step 2 of reacting the halogen-terminated polyisobutylene polymer (B) with a compound (C) having a halogen group and a phenoxy group under the presence a Lewis acid catalyst to prepare a halogenated phenoxyalkyl-terminated polyisobutylene polymer (D), and a step 3 of reacting the halogenated phenoxyalkyl-terminated polyisobutylene polymer (D) with an acrylic acid compound (E) to prepare the (meth)acryloyl-terminated polyisobutylene polymer (A).
