摘要： The invention relates to a method for manufacturing thermoplastic poly(vinyl alcohol) derivative in a melt state reaction and a product thereof, wherein the method thermoplastic poly(vinyl alcohol) that has been dried is heated and admixed with an organic acid anhydride that has a catenated carbon structure which ends into a vinyl group, such that a mixture is obtained which is above the melting point of the mixture, thereby causing an ester bond forming condensation reaction in a melt state, wherein at least some of the organic acid anhydride reacts with hydroxyl groups of the thermoplastic poly(vinyl alcohol), such that reaction product is formed which contains carboxylic acid residue and thermoplastic poly(vinyl alcohol) derivative which contains ester bonded pendant chains of which at least some end into vinyl groups. The invention further relates to a method for manufacturing a paper substrate and a product thereof, which contains a primer layer that contains the reaction product.

摘要： Clean version of the Abstract A preparation method of a heat-not-burn cigarette paper with boron nitride as a thermally-conductive filler incl tides: mixing po .ssiuxr oleate, polyvinyl alcohol (PVA) and water, thoroughly stirring under an ultrasonic condition, aging, and filtering until there is no precipitate; thoroughly mixing a resulting mixed solution with a softwood pulp and a hardwood. pulp to obtain a coarse pulp; and under stirring, adding boron nitride and calcium carbonate as a filler to the coarse pulp, heating to 60° C., and stirring for thorough mixing to obtain a pulp for sizing and papermaking. The present disclosure effectively improves the stability of a cigarette paper by improving a coefficient of thermal conductivity of the paper. Boron nitride, when used as a thermally-conductive filler in a thin-walled or paper product, enables high heat removal capacity. The preparation method retains the original whiteness and transparency of the cigarette paper, and provides high conductivity.

摘要： Provided are a printing sheet having a coating layer for receiving ink on at least one surface of a substrate and having excellent printability, excellent adhesiveness between the substrate and the coating layer, and excellent antistatic performance and thus being less likely to cause troubles such as paper jams during printing, and further having excellent properties such as water resistance and weather resistance in a printing sheet; and a method for producing the same. The printing sheet includes a coating layer formed by blending (meth)acrylic ester-based resin particles in a proportion of 1% by mass or more and 10% by mass or less and clay in a proportion of 50% by mass or more and 70% by mass or less in a continuous phase made of an acrylic polymer.
