Abstract: PURPOSE:To improve the initial adhesive strength and resistance to foaming by compounding a specific copolymer with an alkali and CaCO3. CONSTITUTION:At least one monomer selected from the group consisting of an isobutylene unit, styrene monomer and acrylic acid monomer is copolymerized with a maleic acid monomer at 30-200 deg.C for 0.5-20hr to give a copolymer having a viscosity-average MW of 500-400000. The resulting copolymer is heated to 30 deg.C or higher and mixed with an alkali (e.g. NaOH) to give an alkali- neutralized product having a neutralization degree of 0.05-0.5. Said product is then heated to 30 deg.C or higher, mixed with CaCO3 having a mean particle diameter of 0.01-50mum in an amt. of 5-1000 pts.wt. (based on 100 pts.wt. said copolymer in said neutralized product), and stirred for 0.5-10hr.

Abstract: PURPOSE:To obtain the tile metal salt having well-balanced water absorption and gel strength by adding a crosslinking agent of an epoxy compound and a hydroxy compound to the product formed by reversed phase suspension polymerization of an alkali metal salt of acrylic acid and crosslinking the polymerization product. CONSTITUTION:The reversed phase polymerization of an alkali salt of acrylic acid is conducted in the presence of a solvent such as pentane, a polymerization initiator such as potassium persulfate and a surface active agent, preferably sorbitan monostearate, preferably at 20 to 80 deg.C for 2 to 10 hours. The resultant polymer is combined with a crosslinking agent composed of an epoxy compound such as ethylene glycol glycidyl ether and a hydroxy compound such as ethylene glycol to effect crosslinking preferably at 50 to 150 deg.C for 30 minutes 10 hours to give the subject metal salt which is used as a material for paper diaper or sanitary napkin.

Abstract: PURPOSE:To obtain a fiber treating agent obtained by blending a water soluble acrylic polymer with neutralized product of a specific copolymer and capable of providing excellent strength and elongation to a fiber by giving the agent to the fiber at ambient temperature and simultaneously reduced in releasing amount after treatment. CONSTITUTION:A water soluble acrylic polymer, e.g., poly(meth)acrylic acid is blended with one kind of monomer selected from alpha-olefin, cyclic olefin, diolefin, acrylic monomer, vinyl ether and vinyl sulfide and neulralized material obtained by neutralizing a copolymer (e.g., diisobutylene-maleic acid based copolymer) containing a maleic acid based monomer as a constitutional unit with an alkali agent to provide the aimed treating agent capable of providing excellent strength, etc., to a fiber by subjecting a natural fiber, synthetic fiber, etc., to immersing treatment without heating and simultaneously reduced in releasing amount after treatment. Furthermore, when PVA is further added thereto, the treating agent is further strengthened.
