RELEASE AGENT AND METHOD OF PRODUCING RESIN PRODUCT
A release agent contains a polymer of a polymerizable component containing a (meth)acrylate having a long-chain alkyl group with carbon atoms of 12 to 22 and an acid group-containing ethylenic unsaturated bond-containing monomer, wherein an acid group is neutralized by ammonia and/or amines.
ROOFING, CLADDING OR SIDING PRODUCT
This invention relates to a roofing, cladding, or siding module, comprising an underlapping region extending from a head edge of the module and an exposed region extending from a foot edge of the module. The length of the foot edge defining the length of the module. The underlapping region is adapted to be substantially covered by the exposed region of an adjacent or overlapping module when installed on a building surface. The module is formed of at least one layer of extruded material. The layer so formed comprises at least 40% w/w filler and/or reinforcement, and one or more polymer(s).
ELECTRIC FIELD ”Z“ DIRECTION ALIGNMENT OF NANOPARTICLES IN POLYMER SOLUTIONS
A method of preparing a polymer film having an oriented dispersed material includes casting a multi-layer polymer solution having a first polymer solution layer and a second polymer solution layer where the second polymer solution layer is at least partially immiscible with the first polymer solution layer. The method further includes passing the multi-layer polymer solution through an electric field application zone, to thereby induce orientation of the dispersed material. A multi-layer polymer film can then be formed by drying the solvent from the multi-layer polymer solution. An apparatus for preparing polymer films includes a top electrode made from a flexible metal mesh coated with a non-stick, non-conductive coating.
