  Hydrophobic and low-density amino acid ionic liquids

  摘要：

  A series of tetraalkylphosphonium amino acid salts was synthesized to determine the effect of ion structure, in particular the length of alkyl chains, on physico-chemical properties such as density, viscosity, glass transition temperature, and decomposition temperature. The resulting alkylphosphonium amino acid ionic liquids (AAILs) all had low density, from 0.886 to 0.945 g cm(-3) at 25 degrees C. The density was tunable by varying the alkyl-chain length, regardless of the symmetry of the phosphonium cations. When the alkyl chains on the phosphonium cation were hexyl or longer, the AAILs were phase-separated upon mixing with water because of their hydrophobicity, and floated on top of the water phase. The water content in the ILs depended on the amino acid side chains and on the alkyl-chain length on the cations. (C) 2010 Elsevier B.V. All rights reserved.

  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).
