Description
また、上記式(6)中、R 8 は主鎖の炭素数が2〜20の炭化水素基を表し、gは2〜10であり、g+hは2〜50である。

(3)HC(R2)=CH−
重合体(A)は、1分子中に平均して少なくとも1個、好ましくは1〜5個、より好ましくは1〜3個、さらに好ましくは1〜2個のアルケニル基を有する。重合体(A)1分子中のアルケニル基の数が平均して1個未満では硬化性が不十分になり、また1分子中に含まれるアルケニル基の数が多すぎると網目構造が密になるため、粘着特性が低下する傾向にある。
で表される化合物に相当し、株式会社シーエムシー発行(1990.1.31)の「シリコーンの市場展望−メーカー戦略と応用展開−」にも記載されているように、各種変性シリコーンの原料として用いられている。
粘着剤層の厚さは特に限定なく、例えば10〜5000μmでもよい。
A:末端に少なくとも1個のアルケニル基を有するポリオキシアルキレン重合体
A−1:アリル基末端ポリオキシアルキレン(下記合成例参照、アルケニル基0.12mmol/g含有)
B:両末端にヒドロシリル基を有する化合物、
B−1:シリコンオイル(ヒドロシリル基1.16mmol/g含有)
B−2:シリコンオイル(ヒドロシリル基1.69mmol/g含有)
B−3:シリコンオイル(ヒドロシリル基0.76mmol/g含有)
C:1分子中に平均2個以上のヒドロシリル基を含有する化合物
C−1:シリコンオイル(ヒドロシリル基3.2mmol/g含有)
C−2:シリコンオイル(ヒドロシリル基4.2mmol/g含有)
D:ヒドロシリル化触媒
D−1:白金−1,3−ジビニル−1,1,3,3−テトラメチルジシロキサン錯体(3重量%白金イソプロパノール溶液)。
苛性アルカリを用いた重合法により、数平均分子量3000のオキシプロピレン重合体グリコールを得た。特開平5−117521号公報の合成例1の方法に準じ、そのオキシプロピレン重合体グリコールを開始剤として複合金属シアン化物錯体触媒(亜鉛ヘキサシアノコバルテート)を用いてプロピレンオキシドを重合し、数平均分子量28000の重合物を得た。この重合物に対して、ナトリウムメチラートの28%メタノール溶液と塩化アリルを使用して末端をアリル基に変換した後、脱塩精製して、1分子中に概ね2個のアリル基末端を有するポリオキシアルキレン重合体(重合体(A−1))を得た。得られた重合体のアリル末端基量は0.12mmol/gであった。
特開平5−32783に記載の方法により、ジメチルシロキサンおよびジフェニルシロキサンからなり両末端にヒドロシリル基を有する化合物(B−1)を得た。化合物(B−1)1gあたりのヒドロシリル基量は1.16mmol/gであり、25℃での屈折率は1.482、粘度は54cPであった。
特開平5−32783に記載の方法により、ジメチルシロキサンおよびジフェニルシロキサンからなり両末端にヒドロシリル基を有する化合物(B−2)を得た。化合物(B−2)1gあたりのヒドロシリル基量は1.69mmol/gであり、25℃での屈折率は1.480、粘度は32cPであった。
特開平5−32783に記載の方法により、ジメチルシロキサンおよびジフェニルシロキサンからなり両末端にヒドロシリル基を有する化合物(B−3)を得た。化合物(B−3)1gあたりのヒドロシリル基量は0.76mmol/gであり、25℃での屈折率は1.483、粘度は81cPであった。
下記式(7)で表されるメチルハイドロジェンシリコーン(式中、iは平均5である)に白金触媒存在下、全ヒドロシリル基量の0.5当量のα−メチルスチレンを添加し、1分子中に平均2.5個のヒドロシリル基を有する化合物(化合物(C−1))を得た。この化合物のヒドロシリル基含有量は3.2mmol/gであった。
式(7)で表されるメチルハイドロジェンシリコーン(式中、iは平均10である)に白金触媒存在下、全ヒドロシリル基量の0.5当量のα−メチルスチレンを添加し、1分子中に平均5個のヒドロシリル基を有する化合物(化合物(C−2))を得た。この化合物のヒドロシリル基含有量は4.2mmol/gであった。
重合体A(A−1)に対して、化合物B(B−1、B−2、B−3)および、化合物C(C−1、C−2)を表1に示した重量で混合し、更にヒドロシリル化触媒D(D−1)0.1重量部、2−メチル−3−ブチン−2−オール0.03重量部を十分に混合して粘着剤用組成物を得た。この粘着剤用組成物を室温でシリコーン剥離処理を施した剥離紙の処理面上に、硬化後の厚みが50μmになるように塗工して、130℃で3分間硬化させて粘着剤層を形成した。
上記実施例において得た粘着剤層を、支持体としてポリエステルフィルム(東レ ルミラーフィルム 厚さ25μm)を速度2m/minの条件にて重さ2kgのゴムローラーを用いてラミネートし、粘着シートを得た。幅25mmに切断し、重さ2kgのゴムローラーを速度2m/minの条件でSUS304の板に貼付し、1時間放置した。各テープをSUS304板から300mm/minの速度にて180°の角度で剥がす際の応力を粘着力の測定値とした。結果を表1に示す。
