Provided is a process for the production of a fluorine-containing block copolymer, which suppresses the formation of a homopolymer as a by-product and which, regardless of whether the chain transfer constant of the iodine end is large or small, achieves nearly 100% conversion into a block copolymer. The process is characterized by reacting (A) a fluorine-containing polymer which has an iodine atom or a bromine atom at either or both terminals of the backbone chain and/or at a side-chain terminal with (M) a radical-polymerizable monomer in the presence of (C) a sulfur compound represented by general formula (2): (Y 1 )nH2-nS 2 Q 4 (wherein Y 1 is a mono- or divalent metal ion or an ammonium ion; and n is an integer of 0 to 2).

The invention provides a hydrophilizing agent which is to be added to a polymer having a large contact angle to produce a porous polymer film that has a small contact angle and that can maintain this small contact angle even after 168-hour contact with an aqueous sodium hypochlorite solution. The hydrophilizing agent contains a fluoropolymer having a contact angle of 50° or smaller and a weight reduction rate of 7% or lower.

There is provided an actuator element which can be driven at low voltages, is operated stably in air and in vacuo with a quick response, exhibits a large degree of displacement and a large displacement force, has high mechanical strength including flexibility, thus giving long-term durability for repeated use, can be produced by a very simple method, can be formed into a small size because of a simple structure, and can be put into practical use in wide applications. The actuator element is comprised of an ion-conducting layer for an actuator element comprising (I) a fluorine-containing polymer having functional group and (II) an ionic liquid, in which the fluorine-containing polymer having functional group is a polymer having functional group selected from the group consisting of -OH, -COOH, -COOR, -CN, iodine atom, epoxy group and (meth)acryloyl group in a polymer side chain and/or at an end of a polymer trunk chain, and an electrode layer comprising (I) the fluorine-containing polymer having functional group, (II) an ionic liquid and (III) an electroconductive nano-filler.

There are provided novel crosslinked fluorine-containing elastomer fine particles, a process for preparing crosslinked fluorine-containing elastomer fine particles and a resin composition comprising the same. The crosslinked fluorine-containing elastomer fine particles are crosslinked fluorine-containing elastomer fine particles having a gel fraction of not less than 85 % by mass or crosslinked fluorine-containing elastomer fine particles obtained by crosslinking fluorine-containing elastomer particles having at least three iodine atoms per one polymer molecule at an end thereof. The composition is one comprising those fine particles and a synthetic resin. The preparation process is a process for preparing crosslinked fluorine-containing elastomer fine particles, characterized by subjecting peroxide-crosslinkable fluorine-containing elastomer particles to peroxide-crosslinking by heating an aqueous dispersion comprising the fluorine-containing elastomer particles, a peroxide and a polyfunctional unsaturated compound.
