MULTIBLOCK COPOLYMER FILMS, METHODS OF MAKING SAME, AND USES THEREOF
A method for forming an isoporous graded film comprising multiblock copolymers and isoporous graded films. The films have a surface layer and a bulk layer. The surface layer can have at least 1×10.sup.14 pores/m.sup.2 and a pore size distribution (d.sub.max/d.sub.min)) of less than 3. The bulk layer has an asymmetric structure. The films can be used in filtration applications.
ELASTIC FILM AND METHOD FOR PRODUCING AN ELASTIC LAYER MATERIAL
An elastic film has a perforation formed by perforation holes that are elongated along a preferred expanding direction in the unexpanded state, wherein the ratio of the length of the perforation holes determined along the preferred expanding direction to a width of the perforation holes determined perpendicular thereto amounts to at least 3:2. The elongation at break along the preferred expanding direction is at least twice as high as the elongation at break determined perpendicular thereto along the width of the perforation holes.

RESIN COMPOSITION, PREPREG USING SAME, FILM PROVIDED WITH RESIN, METAL FOIL PROVIDED WITH RESIN, METAL-CLAD LAMINATE, AND WIRING BOARD
A resin composition contains a styrenic block copolymer, a radical polymerizable compound, and at least one free radical compound selected from the group consisting of a compound (A) represented by Formula (1), a compound (B) represented by Formula (2), and a compound (C) having two or more of at least one group selected from groups represented by Formulas (3-1) and (3-2).
WATER-SOLUBLE COMPOSITION COMPRISING LYSOPHOSPHATIDYLETHANOLAMINE AND HAVING IMPROVED STABILITY, AND METHOD FOR PREPARING THE SAME
The present invention provides a water-soluble composition including lysophosphatidylethanolamine, an organic solvent, a silane-based auxiliary agent, a surfactant, an antifreeze, and water. According to the water-soluble composition of the present invention, a lysophosphatidylethanolamine effective ingredient is not decomposed well even at a high temperature, and since the composition is stably dissolved in water when diluted in water before applied to crops, the stability of a water-soluble formulation is excellent. In addition, since surface tension is excellent, the composition may be uniformly distributed when treating fruits to show uniform ripening promoting effects of the fruits.
Free-flowing mixture, its use, and method for its production
Disclosed are free-flowing mixtures comprising a granular material comprising a thermoplastic elastomer, a functionalized thermoplastic elastomer, at least one phase change material bound to the thermoplastic elastomers, and at least one binding agent capable of adsorbing and/or absorbing portions of the phase change material. The binding agent is substantially present between the granulate materials, and either: i) the proportion by weight of the phase change material in the granular material is 60% to 90% and the binding agent is a non-silicate binding agent, or ii) the proportion by weight of the phase change material in the granular material is more than 70% and up to 90%. Also described are various compositions comprising the mixture and methods for producing the mixture.
Ionic functionalization of aromatic polymers for ion exchange membranes
The electrochemical energy conversion system of the present disclosure includes an anode, a cathode, and an ion exchange membrane including a polymer having an aromatic polymer chain and an alkylated substrate including an alkyl chain, and at least one ionic group. The alkylated substrate is bound to at least one aromatic group in the polymer chain via Friedel-Crafts alkylation of the at least one aromatic group. The alkylation reaction utilizes a haloalkylated tertiary alcohol or a haloalkylated alkene as a precursor. In the presence of an acid catalyst, a carbocation is generated in the precursor which reacts with the aromatic rings of the polymer chain. The at least one ionic group is then replaced with a desired cationic or anionic group using a substitution reaction. The membranes exhibit advantageous stability achieved through a simplified and scalable reaction scheme.
SINGLE-LAYER MONOLITHIC WATERPROOF BREATHABLE FILM
A monolayer monolithic waterproof-breathable film A with a thickness between 5 and 150 μm consists of at least 50% by weight of a highly breathable polymer. One of its faces exhibits an arithmetical mean roughness Ra of at least 0.1 μm.

The layer B is a peelable layer with a thickness between and 100 μm and consisting of a dispersion of high density polyethylene (HDPE) in a continuous phase of atactic polypropylene. The amount of dispersed HDPE is such that layer B exhibits an arithmetical mean surface roughness Ra of at least 0.1 μm. Stage (ii) of the process includes separating the monolayer film A by peeling off the layer B in the multilayer film M.
