Abstract
It is to provide a polymer having a high antistatic function, a high solubility to solvent and high compatibility to a formulation, and an antistatic agent, curable composition or a water repellent and oil repellent comprising the polymer. It is a linear block polymer, block star polymer or block graft polymer in which at least one block is a block wherein an anion and a counter cation form an onium salt on the polymer chain side, and a composition comprising the same. It is preferred that a linear block polymer has a number average molecular weight of 20000 or less, and a block star polymer and block graft polymer has a number average molecular weight of 10000 or more.
Claims9
A linear triblock polymer, consisting of:
- a) a block comprising an onium salt consisting of an anion on a polymer side chain and a counter cation, and
- b) a block comprising a living anionic polymerization-inactive vinyl group, hydroxyl group or carboxyl group, and
- c) a block comprising a fluorocarbon group or trialkylsilyl group on a polymer side chain;
- wherein:
- the block alignment is in the order of b)-a)-c), and
- the main chain polymer in each block is a (meth)acrylate polymer.
