(カルボン酸変性ニトリル系共重合体ラテックスの製造)
撹拌機、温度計、冷却器、窒素ガスの引込口及び単量体、乳化剤、重合反応開始剤を連続的に投入できるように備えられた10Lの高圧反応器を窒素で置換した後、アクリロニトリル25重量%、1,4−ブタジエン70重量%、メタクリル酸5重量%の単量体混合物100重量部に対して、アルキルベンゼンスルホン酸ナトリウム2.5重量部、t−ドデシルメルカプタン0.5重量部及びイオン交換水140重量部を投入し、40℃まで昇温させた。
前記ラテックス−A100重量部に5重量%に希釈したN−イソプロピルアクリルアミド単独重合体(Mn:35,000g/mol)0.5重量部を混合した。そこに、3%水酸化カリウム溶液及び適量の2次蒸溜水を加え、固形分濃度25重量%、pH10.0のディップ成形用ラテックス状組成物を得た。
12重量部の硝酸カルシウム、87.5重量部の蒸溜水、0.5重量部の湿潤剤(wetting agent)(Teric 320 produced by Huntsman Corporation, Australia)を混合して、凝固剤溶液を製造した。この溶液に手形状のセラミックモールドを1分間浸漬し、取り出した後、80℃で3分間乾燥し、凝固剤を手形状のモールドに塗布した。
