殺生剤(B)、増粘剤(C)および溶剤(D)を必須成
分として含有する懸濁状殺生剤組成物である。That is, the present invention provides a dispersant for a suspended biocide comprising a polystyrene sulfonate having a molecular weight of 1.000 to 200,000, and a dispersion for a suspended biocide comprising a polystyrene sulfonate having a molecular weight of t, ooo to 200,000. agent (A),
This is a suspension biocide composition containing a biocide (B), a thickener (C), and a solvent (D) as essential components.
本発明におけるポリスチレンスルホン酸塩は水に溶解ま
たは分散するものである。The polystyrene sulfonate in the present invention is one that is dissolved or dispersed in water.

ウムの塩であり特に好ましくは、(1)ナトリウムと(
2)カリウムおよび/またはリチウムとの併用塩である
。Salts of polystyrene sulfonate include alkali metal salts such as sodium salt, potassium salt, and lithium salt, alkaline earth metal salts such as calcium salt and magnesium salt, and amine salts such as ethanolamine salt and triethanolamine salt. can be mentioned. Preferred are sodium, potassium, lithium, calcium, and magnesium salts, and particularly preferred are (1) sodium and (
2) It is a salt used in combination with potassium and/or lithium.
併用塩の場合(1)と(2)のモル比は通常99:1〜
1:99である。In the case of combined salts, the molar ratio of (1) and (2) is usually 99:1 ~
It is 1:99.
併用塩の場合ポリスチレンスルホン酸−分子中に二種以
上の塩をもつものが好ましいが、二種以上の塩の混合物
であってもよい。In the case of combined salts, polystyrene sulfonic acid having two or more types of salts in its molecule is preferred, but a mixture of two or more types of salts may be used.
ポリスチレンスルホン酸塩の平均分子量は通常i、oo

性が悪くなる。The average molecular weight of polystyrene sulfonate is usually i, oo
o~200,000 preferably 5,000~100,
It is 000. When the average molecular weight is less than 1,000, the dispersibility in water is insufficient, and when it exceeds 200,000, the dispersibility in water becomes poor.
粘度は30重量%水溶液粘度で示した場合、通常10〜
10,000cps、好ましくは約20〜1 、ooo
Cpsである。The viscosity is usually 10 to 30% when expressed as a 30% by weight aqueous solution viscosity.
10,000 cps, preferably about 20-1, ooo
It is Cps.

.5モル量で得られたものである。The degree of sulfonation of the polystyrene sulfonate is determined by the amount of the sulfonating agent used, which is usually 0.5 to 2 moles per mole of styrene monomer in the raw material polystyrene, preferably 0.6 to 1.
.. It was obtained in a 5 molar amount.
使用モル量が0.5未満では、スルホン化度不十分で水
不溶分が増加し、2モルを越えるとボウ硝などの副生物
が増加しいずれも水中分散性が悪くなる。If the molar amount used is less than 0.5, the degree of sulfonation will be insufficient and water-insoluble matter will increase, and if it exceeds 2 molar, by-products such as sulfur will increase, and in both cases the dispersibility in water will deteriorate.
