摘要:
Alcohol compatible, water-soluble copolymer useful as a corrosion inhibitor. The copolymer includes at least one olefinically unsaturated carboxylic acid monomer, at least one olefinically unsaturated mono- or di-alkyl ester of a di-carboxylic acid monomer, and at least one olefinically unsaturated hydrophilic, non-ionic monomer. The molar ratio of the alkyl ester groups of the mono- or di-alkyl ester of the dicarboxylic acid monomer to the hydrophilic groups of the hydrophilic, non-ionic monomers is from 0.0 1: to 1000:1, and the molar ratio of the sum of the alkyl ester groups and hydrophilic groups of the hydrophilic, non-ionic monomers to the carboxylic acid groups, is from 0.001:1 to 100:1. No haze or precipitate occurs in a mixture of the water-soluble copolymer at 4°C for 15 hrs or more as a 20 weight % aqueous copolymer solution in alcohol at a water-soluble copolymer to methanol weight-ratio of not more than 25 to 100.
摘要:
Difunctional oxazoline resins, which may be produced in a convenient one-step reaction from an arylalkylene dinitrile by reaction with an amino alcohol, are used in compositions with an additional curable compound or resin containing one or more carbon to carbon double bonds. The composition can be cured to a thermoset material, the curing mechanism occurring by the zwitterion polymerization of the bisoxazoline resin with the resin containing the one or more carbon to carbon double bonds. The reaction occurs without the need for curing initiators.(I).
摘要:
Isocyanurate compounds or resins have the structure (I) in which Y is an hydroxyl group -OH or a maleimide group Formula (II) provided that at least one maleimide group is present, and Q is any divalent organic moiety, aliphatic or aromatic.
摘要:
Adhesive compositions containing a base compound or resin and an epoxy resin with vinyl functionality, without a curing agent for the epoxy resin, show enhanced stress performance. The compositions can be used in microelectronic applications.
摘要:
High performance pressure sensitive adhesives are obtained using acrylic block copolymers. These adhesives can be applied from solvent at very high solids and with high levels of enhancer.
摘要:
A hot melt adhesive based on ethylene-2-ethylhexyl acrylate copolymer finds use in packaging applications where high heat resistance, as well as good cold tolerance, is required.
摘要:
The present invention relates to the use of a starch which is crosslinked or inhibited to control and/or regulate the blood glucose level of mammals and post-prandial absorption. Such chemically modified starches, when properly formulated into foods, may be used to provide the consumer with glucose over an extended time period and more constant glucose levels.
