(b)出発物質中のエポキシド基の90〜100%が反応しており、
(c)該付加化合物中の芳香族基の重量分率が50%以下であり、かつ、
(d)該付加化合物は、塩を形成することができるアミノ基を1分子当たり少なくとも1個含むか、または、塩を形成していることを特徴とする付加化合物を提供する。
上記付加化合物の混合物も、湿潤剤及び分散剤として好適である。
(HO)3-nPO(OR1)n
(式中、nは1又は2であり、R1は炭素数5〜20の直鎖状又は分岐状アルキル基、炭素数6〜26のアリール基又はアラールキル基、数平均分子量が100〜5000g/molのオキシアルキル化アルコールの残基、少なくとも1個のカルボン酸エステル基を持ち数平均分子量が400〜5000g/molの残基、および、少なくとも1個のウレタン基を持ち数平均分子量が100〜5000g/molの残基から選ばれた置換基をあらわす)
で表されるリン酸のエステル塩の形であるのが好ましい。
子量が400g/molを超え、1分子当たり、1個の第1級又は第2級アミノ基と少なくとも4個のエーテル結合酸素を有するポリオキシアルキレンモノアミンとを反応させて、出発物質中のエポキシド基の90〜100%を反応させることにより、芳香族基の重量分率が50%以下であり、かつ、塩を形成することができるアミノ基を1分子当たり少なくとも1個有する付加化合物を得る工程、および、該付加化合物を塩に変換する任意の工程とを含むことを特徴とする。
20部のEpikote 1001と、44部のJeffamine M 1000とを混合し、この混合物を窒素雰囲気中、140℃で約4時間、エポキシド基が核磁気共鳴(NMR)分析などで検出されなくなるまで加熱した。この反応溶液の組成は、エポキシド基の1モル当たり1モルの第1級アミノ基を使うように選んだ。黄色の透明な粘性のある反応溶液が得られた。この生成物は、一定時間後晶出し、過熱状態または適当な溶媒で希釈して湿潤剤及び分散剤として使用することができた。
Epikote 1001は、Shell AG社の製品で、比較的分子量の大きい固体のビスフェノールA系エポキシ樹脂である。
実施例1の方法と同様にして、別のエポキシドをアミンと反応させた。第1表に、これらの実験の概要を示す。本実施例においても、(ポリ)エポキシドとアミンは、アミノ基およびエポキシド基が当モル比になるように用いた。確実にこの比になるようにするために、各(ポリ)エポキシドのエポキシド当量と各アミンのアミン価を測定した。
実施例2で得たアミン価(AmN)が24mgKOH/gの反応生成物30部を、酸価(AcN)が112.5mgKOH/gのリン酸モノエステル(HO)2PO(OR1)(R1=ブトキシポリプロピレングリコール)(以下、リン酸エステルAとする)6.4部と約60℃で反応させて塩を形成した。透明で粘性の褐色反応溶液が得られた。この実施例の塩形成率は1であった。
実施例2のエポキシド−アミン付加化合物200部をトール油脂肪酸(酸価:約195mgKOH/g)24.6部と混合した。この組成割合では、アミノ基の数はカルボキシル基の数と等しい。この混合物にp−トルエンスルホン酸触媒0.4gを加え、攪拌しながら160℃まで加熱した。反応で生成した水は、窒素をゆっくり流しながら反応混合物から除去した。この反応条件を約3.5時間保った後、反応温度を200℃まで上げた。さらに、6.5時間後、反応溶液のアミン価は約11mgKOH/gのレベルまで下がった(理論的初期値:約22mgKOH/g)。すなわち、全アミノ基の約50%がトール油脂肪酸のアミド化に消費され、残りのアミノ基は塩を形成していた。黄色みを帯びた褐色の透明反応溶液が得られた。
実施例2のエポキシド−アミン付加化合物200部をアクリル酸ブチル11.1部とMichael反応させた。Anullex BHTを0.25部混合物に加え、反応混合物中の固体が99%を超えるまで窒素雰囲気中100℃で約12時間攪拌した。残留アクリル酸ブチルは真空蒸留で除去した。透明で赤黄色の反応生成物が得られた。Anullex BHTはArchimica社の製品で、遊離基連鎖反応を抑える安定化剤として作用する。
実施例12のAmNが29.1mgKOH/gである反応生成物25部を、実施例6のリン酸エステルB6.7部と反応させて塩を形成した。塩形成率は1であった。透明な赤黄色の反応生成物が得られた。
比較例14及び15では、本発明の付加化合物の優れた効果を示すために、本発明外の脂肪族エポキシドを用いてエポキシド付加化合物を合成した。比較付加物の場合も、エポキシドとアミンの比はアミノ基とエポキシド基が等モル比になるように選んだ。確実にこの比になるようにするために、各(ポリ)エポキシドについてエポキシド当量、各アミンについてアミン価を測定した。
実施例1の方法と同様にして、20部のGrilonit RV 1814を124.7部のJeffamine M2070と反応させた。透明で黄色の反応混合物が得られた。Grilonit RV 1814は、Ems Primid社の製品であり、C13/C15アルキルグリシジルエーテルである。
アミン価(AmN)が23.6mgKOH/gの実施例14で得た反応生成物30部を6.4部のリン酸モノエステルAと約60℃で混合した。塩形成率は1であった。透明な褐色反応混合物が得られた。
実施例1の方法と同様にして、メタクリル酸グリシジル(Mn=142g/mol)15部を197.6部のJeffamine M2070と反応させた。少し濁った、無色から黄色の反応溶液が得られた。
オレイルアミン28.2部、アミノプロピルイミダゾール12.6部、サリチル酸(触媒)1.4gを溶媒としての2−ブトキシエタノール251.2部に加えて、この初期仕込みを70℃まで加熱した。Epikote 828/2−ブトキシエタノール(37.6g/68g)を十分攪拌しながら1分間かけて加えた。次に、この反応溶液を85℃まで加熱し、この温度で4時間撹拌した。固体含有量が約20%、アミン価が約41.5mgKOH/gの透明な黄色の反応溶液が得られた。
比較例17の反応生成物30部を11.3部のリン酸エステルAと反応させて塩を形成した。固体含有量が約42%の透明な黄色の反応生成物が得られた。
本発明の分散剤の有効性をテストするために、種々の付加物及びそのリン酸エステル塩を用いて顔料ペーストを調製した。これと平行して、発明外の比較例14〜18の付加物を用いて顔料ペーストを調製した。
2.Sikkens Setaliet BW(Akzo Nobel Decorative Coatings社製のシリケート石工用塗料)
3.Sikkens Rubbol AZ,高光沢塗料、ベース09(Akzo Nobel Decorative Coatings社製のアルキド樹脂塗料)
上記白色塗料は、塗料の種類及び極性が大きく異なるように選んだ。本発明の付加化合物が、広範囲の着色ペーストに使用する湿潤剤および分散剤として適切であることを強調するためである。
