ることが要求される。Conventionally, synthetic copolymer latexes have been widely used, for example, as binders for paper coating, binders for carpet hack sizing, binders for binding fibers such as nonwoven fabrics and artificial leather, and adhesives for various materials. When a copolymer latex is used for such purposes, it is required that the copolymer latex has high adhesive strength and is excellent in water resistance, blistering resistance due to dry heating, and the like.

して汎用的に用いられる。For example, coated paper uses pigments such as kaolin clay, calcium carbonate, satin white, talc, and titanium oxide on the surface of the base paper to improve the paper's printability and optical properties such as gloss. They are coated with paints whose main components are copolymer latex as a binder and water-soluble polymers such as starch, polyvinyl alcohol, and carboxymethyl cellulose as water-retaining agents or auxiliary binders, and conventionally styrene A styrene-butadiene-based copolymer latex obtained by emulsion polymerization of and butadiene as main monomer components, so-called SB-based latex, is commonly used as a binder.

良が一段と要求されている。Incidentally, in recent years, the production of coated paper has increased significantly as demand for color-printed magazines, pamphlets, and advertisements has increased. In particular, with the trend towards higher speed printing in offset printing, the quality requirements for coated paper and pigment binders are becoming increasingly sophisticated. There is a strong need for improvement. Moreover, this pick strength performance is not related to other print properties, namely wet pick strength,
Since there is a negative correlation with blister resistance, halftone dot reproducibility, etc., there is a growing need for improvements that balance these physical properties to a high level.

討が加えられてきた。Since these properties of coated paper are particularly strongly dependent on the design of the SB latex used as a pigment binder, various studies have been made on the performance of the SB latex.

ゲル分率は単量体組成、重合温度をはじめとした様々な
重合因子によって変化するが、これを所望の水準に調整
する方法は連鎖移動剤の添加が一般的かつ簡便である。For example, it has been confirmed that the proportion of the insoluble portion of a copolymer latex film in solvents such as benzene, toluene, and tetrahydrofuran is the controlling factor for pick strength and blister resistance, so various studies have been conducted from this aspect. Specifically, it has been proposed that excellent performance can be achieved by adjusting the composition and gel fraction of the copolymer in latex to a specific range (Japanese Patent Publication No. 59-3598). , Japanese Patent Publication No. 60-17879, Japanese Patent Application Publication No. 58-4894). The gel fraction of this latex varies depending on various polymerization factors such as monomer composition and polymerization temperature, but a common and simple method for adjusting it to a desired level is to add a chain transfer agent.

うるものではない。However, for boat fishing, the pick strength of coated paper is highest when the gel fraction is in the range of 75 to 95% by weight for SB latex, whereas the blister resistance is lower as the gel fraction is lower. It is recognized that it will be good,
None of the above techniques are fully satisfactory in order to simultaneously improve both pink strength and blister resistance to a high level.

。In addition, the optimal butadiene unit fraction for wet pick strength in offset printing is 34% by weight or less, which is different from the optimal butadiene unit fraction for pink strength.
It was difficult to achieve high levels of both physical properties at the same time.

れるに至っていない。In addition, good halftone dot reproducibility and super calendar stain resistance during coated paper production are particularly important for gravure printing paper. However, since this product is designed to have a high butadiene unit fraction, halftone reproducibility has been improved to a sufficient degree without impairing supercalendar stain resistance. not present.

のものが得られていないのが実状である。Additionally, carpet hack sizing adhesives are generally compositions of copolymer latex blended with fillers such as calcium carbonate or aluminum hydroxide and other additives such as thickeners. This adhesive composition is used in the production of tufted carpets, needle punch carpets, etc., mainly to prevent piles from falling off and to bond with primary base fabrics such as jute. Therefore, in this case, improving the adhesive strength, which is the most important physical property of Carpet 7, is one of the biggest technical challenges in this industry, and therefore, improvements are being considered from the aspect of blending copolymer latex and compositions. However, the reality is that so far nothing has been achieved to a satisfactory level.

を有している。Furthermore, the adhesive side has traditionally been manufactured by dissolving natural rubber, synthetic rubber, etc. in an organic solvent, coating it on a base material, and evaporating the organic solvent, but in recent years, it has become more expensive due to the risk of fire and labor. Due to hygienic issues, there is increasing momentum to use polymer aqueous dispersions (latex) using water as a dispersion medium, and aqueous dispersions of rubber-tackifying resin combinations are being developed (Japanese Patent Publication No. 5728545, JP-A-55-48270, JP-A-58160378, JP-A-58-1
83771). This aqueous dispersion containing synthetic rubber latex and tackifier resin has a solid content of 1
A composition in which 50 to 100 parts by weight of a tackifier resin is added to 00 parts by weight is common, and shows good adhesive properties at a measurement temperature of 20 to 23°C, but shows good adhesive properties at a temperature of 0°C. As for the force, a satisfactory value was not obtained. In addition, there have been proposed products in which adhesive properties can be obtained only by using a rubber latex polymer without the presence of a tackifying resin (Japanese Patent Application Laid-Open Nos. 56-145909 and 57-57707). However, this material has the drawback of extremely low adhesion to polyethylene.

The current situation is that In addition, copolymer latexes with high adhesive strength are also desired for carpets, adhesives, and adhesives.

ことを見いだし、本発明を完成するに至った。Under these circumstances, the present invention has been developed to develop a high-performance co-sponsor to further improve the balance between bulk strength and other properties in coated printing papers, as well as the adhesive strength in carpet pack sizing and adhesives. As a result of various studies aimed at providing polymer latex, we found that conjugated diene,

ができる。Polymerization initiators required to initiate polymerization are those that initiate addition polymerization of monomers by radical decomposition in the presence of heat or reducing substances, such as water-soluble or oil-soluble beroxonisulfate, peroxide, etc. , azobis compounds, etc. are commonly used. Examples include potassium peroxonisulfate, sodium peroxonisulfate, ammonium peroxonisulfate, hydrogen peroxide, L-butyl hydroperoxide, benzoyl peroxide, 2,2-azobisisobutyronitrile, cumene hydroperoxide, etc. Sulfates are most preferably used. The proportion of the polymerization initiator used is usually 0.2 to 1.5% by weight based on the total monomers. The polymerization temperature is generally in the range of 60 to 90°C, but when it is desired to accelerate the polymerization rate or polymerize at a lower temperature, sodium bisulfite, ascorbic acid or its salts, erythorbic acid or its salts, Rongalite are used. The so-called Redo Nox polymerization method can be used, in which a reducing agent such as the following is used in combination with a polymerization initiator.
