More particularly, the binder for a secondary battery prepared by reacting a copolymer including specific repeating units and a crosslinking agent including two or more aldehyde groups has excellent mechanical properties and effectively improves a binding force. The negative electrode and the secondary battery including the binder for a secondary battery effectively suppress expansion of a negative electrode to manufacture a secondary battery having excellent charge/discharge cycle characteristics and battery performance.

The present invention relates to a polymer comprising repeating units derived from at least one first monomer (monomer A) which is a molecule comprising a thiolactone ring and an ethylenically unsaturated, polymerizable double bond, and at least one second monomer (monomer B) which is N-vinyl pyrrolidone. Furthermore the present invention relates to a modified polymer, the structure of which is identical to the structure of the said polymer apart from the only difference, which is that all or at least some of the thiolactone moieties of the said polymer are modified by opening the thiolactone ring with a substance selected from the group consisting of ammonia, a primary amine, 2-amino-1-ethanol and L-lysine, wherein the N-atom of said substance is binding to the carbonyl group of the opened thiolactone ring. Furthermore, the present invention relates to a process for making the modified polymer and to the use of the polymer or of the modified polymer for treating hair.

A problem to be solved of the present invention is to provide a diverting agent which gradually dissolves in water. The present invention relates to a diverting agent containing a polyvinyl alcohol-based resin and a method of filling a fracture using the diverting agent.

The present invention provides a method for manufacturing an optical resin composition that is less colored and that has a sufficiently low water absorbability. The optical resin composition manufacturing method according to the present invention includes performing a heat treatment of a fluorine-containing polymer under an atmosphere having a water vapor concentration of 100 volppm or less, the fluorine-containing polymer being obtained by polymerization of a monomer group including a fluorine-containing compound having a carbon-carbon double bond using an organic peroxide. In the optical resin composition manufacturing method, for example, the heat treatment causes thermal decomposition of a terminal group of the fluorine-containing polymer and volatilization of a low-molecular compound generated by the thermal decomposition.
