Abstract:
PROBLEM TO BE SOLVED: To provide a new diallylamine-based copolymer, and a method for producing the copolymer. SOLUTION: The diallylamine-based copolymer has a constituent unit derived from diallylamines, a constituent group derived from an allyl compound, and a constituent unit derived from sulfur dioxide. The method for producing the diallylamine-based copolymer involves copolymerizing monomers forming each constituent unit in a polar solvent in the presence of a radical initiator.

PROBLEM TO BE SOLVED: To efficiently and economically prevent deterioration of UV printing, etc., caused by a large amount of ultraviolet rays by adding an aromatic compound containing no phenolic hydroxyl group to an acrylic tacky agent. SOLUTION: This method for preventing ultraviolet deterioration of a tacky agent comprises adding (B) an aromatic compound containing no phenolic hydroxyl group, preferably an aromatic carboxylic acid ester (e.g. trimellitic acid trioctyl ester, etc.), to (A) an acrylic tacky agent preferably using a polymer obtained by polymerizing a monomer containing >=50 wt.% of a 9-14C alkyl group-containing acrylic acid or methacrylic acid alkyl ester-based monomer. The amount of the component B is preferably 0.1 wt.% based on the component A.

PROBLEM TO BE SOLVED: To obtain the subject composition having excellent water-resistance and mechanical stability and exhibiting balanced tacky adhesive properties by using a specific surfactant in an amount within a specific range based on a (meth)acrylic resin emulsion. SOLUTION: This composition contains (A) a (meth)acrylic resin emulsion and (B) 0.1-5.0 pts.wt. (based on 100 pts.wt. of the polymer component in the component A) of an ammonium salt and/or a lower amine salt of a 10-22C carboxylic acid (preferably oleic acid or lauric acid). The composition may be further incorporated with (C) 0.1-5.0 pts.wt. of a nonionic thickener and further (D) 0.1-30 pts.wt. of a tackifier based on 100 pts.wt. of the polymer in the emulsion. The component C is especially preferably a polyvinyl alcohol modified with an 8-20C alkyl group. The emulsion is stabilized, the mechanical stability is improved, the performance of a surfactant is inactivated by drying in the production of a tacky adhesive product and the retention of water- resistance is expectable by the use of this composition.

PROBLEM TO BE SOLVED: To provide a method for producing alkali cellulose, in which the cellulose polymerization degree decreases little and few bases are used, and to provide a method for producing cellulose ether using the obtained alkali cellulose.SOLUTION: [1] The method for producing alkali cellulose includes: a step 1 for pulverizing a cellulose-containing raw material in the presence of 0.6-1.5 mol of a basic compound per 1 mol of an anhydroglucose unit constituting the cellulose in the cellulose-containing raw material and under the condition in which the moisture content in the cellulose-containing raw material is ≤10 mass% relative to the cellulose, and thereby obtaining a cellulose powder mixture having a median size of the cellulose-containing raw material of ≤150 μm; and a step 2 for obtaining pulverized alkali cellulose by adjusting the moisture content in the obtained cellulose powder mixture to 30-100 mass% relative to the cellulose in the cellulose-containing raw material used in the step 1 as a consequence of adding water to the cellulose powder mixture. [2] The method for producing cellulose ether produces the cellulose ether by means of the reaction between the alkali cellulose produced in the production method and an etherification agent.

Abstract:
PROBLEM TO BE SOLVED: To obtain the subject composition exhibiting coating stability, etc., such as leveling property by compounding a (meth)acrylic resin emulsion with alkyl-modified polyvinyl alcohols having a viscosity higher than a specific level and a viscosity lower than a specific level, respectively, at the optimum weight ratio. SOLUTION: This composition contains (A) a (meth)acrylic resin emulsion, (B) an alkyl-modified polyvinyl alcohol having a viscosity of =7,000 mPa.s in the form of a 5 wt.% aqueous solution. The components B and C are combined with each other at a B/C weight ratio of 50/50 to 95/5. The sum of the components B and C is preferably 0.1-1.5 wt.% based on the component A. Since the composition has good coating stability such as leveling property in applying to a releasing substrate and has good storage stability of the tacky adhesive agent, a tacky adhesive product such as a tacky adhesive sheet and tape can be produced in high efficiency.
