An object of the present invention is to provide a sealing method using a cover film where a problem of odor is not likely to occur and quick drying properties and sealability are high.

The sealing method according to the present invention is a sealing method that is performed using at least a cover film and a sealing solvent, the cover film including a polymer layer provided on a transparent support, in which the sealing solvent is a solvent including at least one kind selected from the group consisting of an ester, an alcohol, a ketone, an ether, and an aromatic hydrocarbon, in a case where the sealing solvent is an ester, an alcohol, a ketone, or an ether, a boiling point of the sealing solvent is 80° C. to 170° C., and in a case where the sealing solvent is an aromatic hydrocarbon, a boiling point of the sealing solvent is 150° C. to 170° C.

Provided is a (meth)acrylic ester copolymer (B) having a reactive silicon group represented by the following formula (1): —SiR.sup.5.sub.cX.sub.3-c (1). R.sup.5 is a substituted or unsubstituted hydrocarbon group having 1 to 20 carbon atoms, X is a hydroxy group or a hydrolyzable group, and c is 0 or 1. A monomer component of the copolymer includes a (meth)acrylic ester (b1), a (meth)acrylic ester polymer (b2) having more than one (meth)acryloyl groups per molecule, and a chain transfer agent (b3) having a mercapto group. The monomer component further includes a monomer (b4) having a reactive silicon group and a polymerizable unsaturated group, and/or the chain transfer agent (b3) having a mercapto group further has a reactive silicon group.

The present invention provides a polymer composition comprising a polymer and an antioxidant comprising a diarylamine-based compound represented by General Formula (1): ##STR00001##
where, in General Formula (1), A.sup.1 and A.sup.2 each independently represent a C.sub.6 to C.sub.18 arylene group which may have a substituent, and A.sup.3 and A.sup.4 each independently represent an organic group having a cyclic imide structure which may have a substituent.

The present invention discloses novel calibrants containing between 1 and 5 iodine atoms and methods of making them using linear polymers, hyperbranched polymers, and biological polymers (including but not limited to proteins and peptides.) Methods of using the calibrants are also disclosed, such as mass spectrometry. The novel calibrants disclosed herein have a more cost- and time-efficient synthesis than other calibrants.

The presently claimed invention relates to an amine-modified polymer and method for preparation thereof. The presently claimed invention is also directed to the use of the polymer as dispersant in ink and coating compositions. Polyacrylate polymer is obtained by controlled free radical polymerization of a mixture comprising at least one acrylate monomer. The post-modification of polyacrylate polymers yields amine-modified polymers that provide improved viscosity parameters, without sacrificing the advantages of a well-defined polymer structure.

Provided are a solid electrolyte composition including an inorganic solid electrolyte, binder particles, and a dispersion medium, in which the inorganic solid electrolyte has a conductivity of ions of metals belonging to Group I or II of the periodic table and includes a sulfur atom, and the binder particles are constituted of a polymer having a macromonomer having a mass average molecular weight of 1,000 or more combined therewith as a side chain component and having at least one group from a group of functional groups (b) below, an electrode sheet for a battery and an all solid state secondary battery which are produced using the solid electrolyte composition, a method for manufacturing an electrode sheet for a battery, and a method for manufacturing an all solid state secondary battery. group of functional groups (b) a carboxyl group, a sulfonic acid group, a phosphoric acid group, and a phosphonic acid group.

Solution casting a nanostructure. Preparing a template by ablating nanoholes in a substrate using single-femtosecond laser machining. Replicating the nanoholes by applying a solution of a polymer and a solvent into the template. After the solvent has substantially dissipated, removing the replica from the substrate.
