Electrophotographic printing techniques offer excellent image quality, but image adhesion to a desired substrate may be problematic in many instances. Primer coatings for improving image adhesion to a substrate may be formed from primer compositions comprising a fluid and an amine-functionalized copolymer dispersed in the fluid as an emulsion, in which the amine-functionalized copolymer has an amine number of about 10 to about 180 mg KOH/g copolymer. The fluid may be aqueous or organic. Suitable amine-functionalized copolymers may be formed by an emulsion polymerization reaction of one or more first ethylenically unsaturated monomers lacking an amine group and one or more second ethylenically unsaturated monomers bearing at least one amine group. The at least one amine group comprises a side chain of the amine-functionalized copolymer.

The present disclosure belongs to the technical field of hemostatic materials, and specifically relates to a degradable hemostatic sponge and a preparation method and use thereof, and a degradable drug-loaded hemostatic sponge. The degradable hemostatic sponge provided by the present disclosure is prepared from raw materials including a crosslinking-modified starch and a cellulose through freeze-drying, where a mass ratio of the crosslinking-modified starch to the cellulose is (0.2-5):1. The degradable hemostatic sponge provided by the present disclosure has a high water-absorbing rate and a large water-absorbing capacity, shows a high support strength and a long support time after water absorption, and is made from plant-derived raw materials and thus may be completely biodegraded. The degradable drug-loaded starch hemostatic sponge provided by the present disclosure has a drug-loaded coating attached to a surface of the sponge, where the drug is slowly released while a support is maintained.

Disclosed is a latex composition for dip molding comprising a carboxylic acid-modified nitrile copolymer latex and starch and an article produced therefrom. Advantageously, a dip-molded article having low syneresis, less stickiness and superior tensile strength can be obtained by using the carboxylic acid-modified nitrile latex in conjunction with starch.
