摘要： In the adhesion of metallic materials to polymers, new adhesive agents of nitrogen containing hetrocyclic polymers such as compositions of imidazole-pyrridine, pyrrolidone-pyridine, and imidazole-pyrrolidone solutions have been discovered as useful. These agents also exhibit anti-corrosion effects. Adhesion and/or reduction of anti-corrosion can be accomplished by pre-coating the metal material with at least one of these agents prior to applying the polymer, or by preblending the polymer with at least one of these agents followed by applying the blend to the metal, under suitable conditions.

摘要： A flexible superabsorbent binder polymer composition including a monoethylenically unsaturated polymer, such as carboxylic acid, sulphonic acid, or phosphoric acid, or salts thereof, and an acrylate or methacrylate ester that contains an alkoxysilane functionality, or a monomer capable of co-polymerization with a compound containing a trialkoxysilane functional group and subsequent reaction with water to form a silanol group wherein the flexible superabsorbent binder polymer composition has a residual monoethylenically unsaturated monomer of less than about 1000 ppm. The flexible superabsorbent binder polymer composition is particularly suitable for use in manufacturing absorbent articles. A method of making the flexible superabsorbent binder polymer composition includes preparing a monomer solution, adding the monomer solution to an initiator system, and activating a polymerization initiator within the initiator system.
