生成した含水クラムを洗浄する洗浄工程と、
洗浄した含水クラムを乾燥する乾燥工程と、

上記脱水バレル及び乾燥バレルのスクリュー部で脱水及び乾燥されたアクリルゴムは、スクリュー型押出機の先端部付近に設けられた、スクリューの無い整流のダイ部に送られる。スクリュー部とダイ部の間には、ブレーカープレートや金網を設けてもよいし、設けなくてもよい。
ゴム組成物としては、上記本発明のアクリルゴムを含むゴム成分、充填剤及び架橋剤を含むことにより耐熱性と耐水性が高度にバランスされ好適である。

アクリルゴムにおける単量体組成に関して、アクリルゴム中の各単量体単位の単量体構成はH-NMRで確認し、アクリルゴム中に反応性基の活性が残存していること及びその各反応性基含有量を下記方法で確認した。また、各単量体単位のアクリルゴム中の含有割合は、各単量体の重合反応に用いた使用量及び重合転化率から算出した。具体的には、重合反応は乳化重合反応でその重合転化率は、未反応の単量体がいずれも確認できない略100%であったことから、ゴム中の各単量体単位の含有割合は各単量体の使用量と同一とした。
アクリルゴム中の反応性基の含有量は、下記方法により測定した。
(1)カルボキシル基量は、ゴム試料(アクリルゴム)をアセトンに溶解し水酸化カリウム溶液で電位差滴定を行うことにより算出した。
(2)エポキシ基量は、ゴム試料をメチルエチルケトンに溶解し、それに規定量の塩酸を加えてエポキシ基と反応させ、残留した塩酸量を水酸化カリウムで滴定することにより算出した。
(3)塩素量は、ゴム試料を燃焼フラスコ中で完全燃焼させ、発生する塩素を水に吸収させ硝酸銀で滴定することにより算出した。
ゴム試料中に含まれる灰分量(%)は、JIS K6228 A法に準じて測定した。
ゴム試料の灰分中の各成分量(ppm)は、上記の灰分量測定の際に採取した灰分をΦ20mmの滴定濾紙に圧着し、ZSX Primus(Rigaku社製)を用いてXRF測定した。
ゴム試料のゲル量(%)は、メチルエチルケトンに対する不溶解分の量であり、以下の方法により求めた。
ゴム試料0.2g程度を秤量(Xg)し、100mlメチルエチルケトンに浸漬させて室温で24時間放置後、80メッシュ金網を用いてメチルエチルケトンに対する不溶解分を濾別した濾液、すなわち、メチルエチルケトンに溶解するゴム成分のみが溶解した濾液を蒸発乾燥固化させた乾燥固形分(Yg)を秤量し、下式により算出した。
ゲル量(%)=100×(X-Y)/X
ゴム試料の重量平均分子量(Mw)は、溶媒としてジメチルホルムアミドに塩化リチウムが0.05mol/L、37%濃塩酸が0.01%の濃度でそれぞれ添加された溶液を用いたGPC-MALS法により測定される絶対分子量及び絶対分子量分布である。具体的には、GPC(Gel Permeation Chromatography)装置に多角度レーザ光散乱光度計(MALS)及び示差屈折率計(RI)を組み入れ、GPC装置でサイズ分別された分子鎖溶液の光散乱強度及び屈折率差を、溶出時間を追って測定することにより、溶質の分子量とその含有率を順次計算し求めた。GPC装置による測定条件及び測定方法は、以下のとおりである。
カラム:TSKgel α-M 2本(φ7.8mm×30cm、東ソー社製)
温度:カラム 40℃
流速:0.8ml/mm
試料調整:試料10mgに溶媒5mlを加え、室温で緩やかに撹拌した(溶解を視認)。その後0.5μmフィルターを用いてろ過を行った。
注入量:0.200ml
ゴム試料のガラス転移温度(Tg)は、示差走査型熱量計(DSC、製品名「X-DSC7000」、日立ハイテクサイエンス社製)を用いて測定した。
ゴム試料の含水量(%)は、JIS K6238-1:オーブンA(揮発分測定)法に準じて測定した。
ゴム試料のムーニー粘度(ML1+4,100℃)は、JIS K6300の未架橋ゴム物理試験法に従って測定した。
ゴム試料の耐水性は、JIS K6258に準拠してゴム試料の架橋物を温度85℃の蒸留水中に100時間浸漬させて浸漬試験を行い、浸漬前後の体積変化率を下記の式に従って算出し、比較例1を100とする指数で評価した(指数が小さいほど耐水性に優れる)。
浸漬前後の体積変化率(%)=((浸漬後の試験片体積-浸漬前の試験片体積)/浸漬前の試験片体積)×100
ゴム試料の耐熱性評価は、ゴム試料の架橋物を175℃で250時間静置する加熱試験を行い、試験前後のゴム架橋物の引張強度をJIS K6251、硬さをJIS K6253に準じて測定し、切断伸びの変化及び硬さの変化を下記の基準で評価した。
切断伸びの変化は、破断伸び変化率が20%以下である場合は「◎」とし、破断伸び変化率が20%を超える場合は「×」として評価した。硬さの変化は、硬さ変化率が20ポイント以下の場合は「◎」とし、硬さ変化率が20ポイントを超えた場合は「×」として評価した。
