    摘要： As a characteristic that had not been known conventionally at all, “permeability potential under pressure (PPUP)” of a particulate water absorbing agent is regulated, and further, “range of particle size distribution” and “coloring” are concomitantly regulated. The present invention is directed to a particulate water absorbing agent having the following (a) to (c): (a) permeability potential under pressure (PPUP) being 50 to 100%; (b) yellowness index (YI) being 0 to 10, and rate of change of yellowness index (ΔYI) being 100 to 150% following a coloring acceleration test for 14 days at 70±1° C. and the relative humidity of 95±1%; and (c) particles of smaller than 150 μm specified by standard sieve classification accounting for 0 to 5% by weight, weight average particle diameter (D50) being 200 to 550 μm, and logarithmic standard deviation (σζ) of particle size distribution being 0.20 to 0.40.

    摘要： A process for the preparation of graft polymers from ethylene homopolymers or copolymers and olefinically unsaturated monomers, especially from ethylene/vinyl ester copolymers, in the presence of a radical forming agent in homogenous or heterogeneous phase, in which a mixture of (meth)acrylonitrile, at least one aromatic vinyl compound and vinylchloride are polymerized in the presence of an ethylene homopolymer or copolymer. The products obtained contain no ungrafted styrene/acrylonitrile copolymer and more than 80% by weight of the graft polymer is chemically almost uniform in structure. The products obtained according to the invention are eminently suitable for use as coating materials and as materials which can be thermoplastically processed.

    摘要： NONAQUEOUS DISPERSIONS OF COPOLYMERS OF (1) AT LEAST ONE ETHYLENICALLY-UNSATURATED MONOMER, (2) A HYDROXYALKYL ESTER OF AN UNSATURATED ALIPHATIC MONOCARBOXYLIC ACID, AND (3) A DIFFERENT HYDROXY-CONTAINING ETHYLENICALLY UNSATURATED MONOMER, WHICH DISPERSIONS ARE STABLE PER SE AND IN THE PRESENCE OF AMINOPLAST RESINS AND SOLUTIONS THEREOF, AND THE COPOLYMERS ARE INTERNALLY COMPATIBLE. THE DISPERSIONS ARE PREPARED BY THE PROCESS WHICH COMPRISES FIRST PARTIALLY POLYMERIZING A PORTION OF AT LEAST ONE OF THE HYDROXY-FREE AND CARBOXY-FREE MONOMERS WITH ALL OF THE DIFFERENT HYDROXY-CONTAINING ETHYLENICALLY UNSATURATED MONOMER, FOLLOWED BY ADDING ALL OF THE REMAINING MONOMERS AND HOLDING TO ESSENTIALLY COMPLETE CONVERSION. THE DISPERSIONS ARE USEFUL IN COATING COMPOSITIONS.
