This invention relates to a sound deadener composition, comprising at least two carboxyl functional polymers with different glass transition temperatures (Tg); at least one organic compound with at least two aziridinyl groups per molecule; and water. The reaction between at least two carboxyl functional polymers with different glass transition temperatures (Tg) and at least one organic compound with at least two aziridinyl groups per molecule forms an IPN structure reaction product so that the cured product of the sound deadener composition according to the present invention exhibits widened temperature range for effective damping.

Coated articles, methods and coating compositions containing (a) a crosslinkable carboxyl-functional acrylic polymer made by polymerizing monomers including acidic monomer, multi-ethylenically unsaturated monomer and optional styrene or substituted styrene, and (b) a nitrogen-containing carboxyl-reactive crosslinking agent such as a beta-hydroxyalkylamide or beta-hydroxyalkylurea compound. The coating composition is useful in coating metal substrates including interior or exterior surfaces of food or beverage cans. The cured coating compositions can exhibit both good flexibility and high Tg.

The present disclosure relates to a preparation method for a super absorbent polymer film. Specifically, it relates to a preparation method for a new type of super absorbent polymer film, which is thin and exhibits excellent absorption performance. In addition, the super absorbent polymer film of the present disclosure has excellent flexibility and excellent mechanical properties, is free from scattering or leaking, and does not require an auxiliary substance such as pulp, so that products can be made thinner and the manufacturing process and costs may be reduced.

The present invention relates to an improved formaldehyde-free coated fibrous substrate. The coating includes a crosslinked binder system which forms three dimensional networks when heat cured. After the coating is applied to the back of fibrous substrate and cured, the coating is capable of hygroscopic expansion which imparts excellent anti-sag properties. The coating is compatible with other coating systems with neutral or mild alkaline pH. The improvement being the binding system is neutralized with a volatile base so that it evaporates quickly so as not to hinder the cross-linking reaction.

The invention relates to compositions and methods of treatment employing compositions comprising polyelectrolyte complexes. The compositions include a water-soluble first polyelectrolyte bearing a net cationic charge or capable of developing a net cationic charge and a water-soluble second polyelectrolyte bearing a net anionic charge or capable of developing a net anionic charge. The total polyelectrolyte concentration of the first solution is at least 110 millimolar. The composition is free of coacervates, precipitates, latex particles, synthetic block copolymers, silicone copolymers, cross-linked poly(acrylic) and cross-linked water-soluble polyelectrolyte. The composition may be a concentrate, to be diluted prior to use to treat a surface.
