摘要:
An aqueous dispersion of 0.1 to 15 percent by weight of at least one phosphate ester and a copolymer formed by the copolymerization of a monomer mixture comprising:
a) 0.1 to 15 percent by weight of at least one dicarboxylic acid, b) 0.1 to 10 percent by weight of at least one functional monomer is represented by the following formula: where R 1 , R 2 and R 3 are hydrogen or a methyl group, R 4 is an alkyl containing 1 to 4 carbon atoms, n is 0 or 1, X is selected from the group consisting of hydrogen, carboxyl, phenyl, aryl, alkyl or alkaryl groups containing 1 to 30 atoms, and Y is a nucleophilic group selected from -OH, -NH 2 or wherein R 5 is a hydrogen, an alkyl containing 1-20 carbon atoms, or an aryl group, and c) more than 80% by weight of backbone monomers.

@ A latex that is devoid of formaldehyde-containing monomers in polymerized form, does not evolve formaldehyde nor decomposes to produce formaldehyde is used in the production of impregnated or treated paper and woven and nonwoven fabrics. The latex is produced by polymerizing a monomer charge containing at least one principal monomer and a crosslinking agent combination consisting of 0.1 to 10 weight parts of a monounsaturated dicarboxylic acid containing 4 to 6 carbon atoms and 0.1 to 10 weight parts of an amide containing 3 to 8 carbon atoms that does not produce formaldehyde. based on a total of 100 weight parts of all monomers that are polymerized. The articles made with the cured latex are characterized by softness, high wet tensile strength, toughness and other physical properties that reflect a different balance of properties.
摘要:
A nonwoven fabric comprising polyester fibers bonded with a water-insoluble, hydrophobic emulsion polymer of 50 to 80 parts by weight of an ethylenically unsaturated monomer selected from styrene, methyl methacrylate and a-methyl styrene, and 50 to 20 parts of a diene monomer selected from butadiene and isoprene, said polymer having a Tg in the range of -5°C to +25°C.
摘要:
A nonwoven fabric comprising hydrophobic polyester fibers bonded with a water-insoluble, hydrophobic emulsion polymer of 50 to 95 parts by weight of a C, to C 2 alkyl acrylate; 5 to 30 parts of an ethylenically unsaturated monomer selected from styrene, methyl methacrylate, and a-methyl styrene; and 0.1 to 5 parts of a monoethylenically unsaturated carboxylic acid containing 3 to 6 carbon atoms.
摘要:
A nonwoven fabric repellent to body fluids and having reduced odor on sterilization by irradiation or steam is made by bonding nonwoven fibers with a latex, forming said nonwoven fabric, and sterilizing said fabric, said latex is prepared by polymerizing, in the presence of 0.1 to 2 weight parts of a free radical initiator and a sufficient amount of a nonionic or anionic emulsifier, 65 to 85 weight parts of a soft hydrophobic monomer having Tg of -80°C to -20°C, 10 to 30 weight parts of a hard hydrophobic monomer having Tg of +40°C to +120°C, 0.1 to 5 weight parts of an unsaturated carboxylic acid containing 3 to 6 carbon atoms, and 0.1 to 5 weight parts of N-alkylol acrylamide or methacrylamide containing 1 to 10 carbon atoms, said latex has post-added and admixed therein 0.01 to 5 weight parts of an odor inhibition agent selected from amine-type antioxidants and hindered phenols that function to reduce odor of said fabric on sterilization thereof.
