• Catalytic activity of cyclophosphazenic polypodands in phase-transfer reactions. Comparison with open-chain analogues.

  日期：1991.8

  The catalytic activity of cyclophosphazenic polypodans 1a-c was evaluated in typical reactions performed under solid-liquid (SL) and liquid-liquid (LL) phase-transfer catalysis (PTC) conditions. Such activity is largely determined by the complexation extent of 1a-c, which is, in turn, related to the number of binding sites of the ligand (1a < 1b less-than-or-equal-to 1c) and to the nature of the inorganic salt M+Y- (Na+ > K+ >> Rb+ and SCN- approximately I- > Br-). Also the presence of water was found to play an important role. Comparison with open-chain analogues PEG 2 and TRIDENT 3 showed that polypodands 1a-c, due to their excellent stability, simplicity of preparation and high complexing ability, can be considered promising phase transfer catalysts, especially under SL-PTC conditions.

  There is provided a highly branched lipophilic polymer that is excellent in blending and dispersing properties in a matrix resin, and is possible to provide surface modification properties such as excellent lipophilicity (anti-fingerprint property) and the like to a coating that is obtained from the resin composition while the intrinsic transparency of the resin is not impaired; and a photopolymeizable composition comprising the highly branched lipophilic polymer. A highly branched lipophilic polymer obtained by polymerizing a monomer A containing two or more radically polymerizable double bonds per molecule and a monomer B containing a C 6-30 alkyl group or a C 3-30 alicyclic group and at least one radically polymerizable double bond per molecule in the presence of 5 to 200 mol % of a polymerization initiator C relative to the number of moles of the monomer A. A photopolymeizable composition comprising the highly branched lipophilic polymer.
