式中、Xは、ハロゲンであり、各Rは、HまたはC1〜C20アルキル基から独立して選択され;上記n個の繰り返し単位のうち約50%以下が、3個以上の連続する単位のブロックにある;を含む部分ハロゲン化溶液合成ジエンゴム(「ハロゲン化溶液重合ジエンゴム」ともいう)と;補強フィラーと;硬化剤と;を混合することを含む。
実施例1において、対照の低ビニルポリブタジエンを合成した。攪拌機を備えた、2ガロンのN2がパージされている反応器に、0.79kgのヘキサンおよび3.69kgのブタジエン(ヘキサン中22.2重量%)を添加した。反応器に、4.96mlのヘキサン中n−BuLi(1.60M)を投入し、反応器ジャケットを60℃に加熱した。25分後、バッチ温度のピークが111℃であった。さらなる30分の後に、ポリマーセメントを、ブチル化ヒドロキシトルエン(BHT)を含有するイソプロパノールにおいて凝析させ、ドラム乾燥した。これを2回行い、対照のポリブタジエンおよび塩素化用のベースのポリブタジエンを生成した(以下参照)。
実施例2において、対照の高ビニルポリブタジエンを以下のように合成した。攪拌機を備えた、2ガロンのN2がパージされている反応器に、0.79kgのヘキサンおよび3.69kgのブタジエン(ヘキサン中22.2重量%)を添加した。反応器に、4.96mlのヘキサン中n−BuLi(1.60M)および2.44mlのヘキサン中2,2−ビス(2’−テトラヒドロフリル)プロパン(1.6M)を投入し、次いで、反応器ジャケットを60℃に加熱した。15分後、バッチ温度のピークが96℃であった。さらなる30分の後に、ポリマーセメントを、ブチル化ヒドロキシトルエン(BHT)を含有するイソプロパノールにおいて凝析させ、ドラム乾燥した。これを2回行い、対照のポリブタジエンおよび塩素化用のベースのポリブタジエンを生成した(以下参照)。
実施例3において、ハイシスポリブタジエンを合成した。10.84mLのメチルアルミノキサン(MAO、3.03M)および2.53mLのブタジエン(22.2%)、0.59mLのNdV3(0.537M)および6.17mlの水素化ジイソブチルアルミニウム(DIBAH、1.08M)を混合することによって、ネオジム触媒を調製した。2分後、混合物に1.19mLの塩素化ジエチルアルミニウム(DEAC、1.07M)を添加し、14分間時効させた。
実施例4〜6において、実施例1の低ビニルポリブタジエンの塩素化を行った。25gの各ポリマーを、500mlのCH2Cl2に溶解した。CH2Cl2に溶解したPCl5(実施例4では4g、実施例5では6g、実施例6では8g)を各混合物に0〜5℃で添加し、室温で一晩撹拌した。ポリマーと反応したPCl5の量を、ポリマー中の塩素含有率で決定した。塩素化ポリマーを、ブチル化ヒドロキシトルエン(BHT)を含有するエタノールにおいて凝析させ、真空乾燥した。塩素化ポリマーはゲルを含まなかった。
実施例7〜9において、実施例2の高ビニルポリブタジエンの塩素化を行った。25gの各ポリマーを、500mlのCH2Cl2に溶解した。CH2Cl2に溶解したPCl5(実施例7では4g、実施例8では6g、実施例9では8g)を各混合物に0〜5℃で添加し、室温で一晩撹拌した。ポリマーと反応したPCl5の量を、ポリマー中の塩素含有率で決定した。塩素化ポリマーを、ブチル化ヒドロキシトルエン(BHT)を含有するエタノールにおいて凝析させ、真空乾燥した。塩素化ポリマーはゲルを含まなかった。
実施例10および実施例11において、実施例3のハイシスポリブタジエンを塩素化した。実施例10および実施例11の両方において、10gのポリマーを、400mlのCH2Cl2に溶解した。CH2Cl2に溶解したPCl5(実施例10では6g、実施例11では12g)を各混合物に0〜5℃で添加し、室温で1時間撹拌した。反応したPCl5の量を、ポリマー中の塩素含有率で決定した。塩素化ポリマーを、ブチル化ヒドロキシトルエン(BHT)を含有するエタノールにおいて凝析させ、真空乾燥した。塩素化ポリマーはゲルを含まなかった。
比較例12は、比較目的で付与した市販のハイシスポリブタジエンであった。表1は、その特性を列挙する。
比較例として、一般的に用いられている塩素化剤、トリクロロイソシアヌル酸(TCCA)を、数種の異なる溶媒および種々の塩素化条件で、低ビニルポリブタジエン、高ビニルポリブタジエン、およびハイシスポリブタジエンと組み合わせて試験した。TCCAは、親水性溶媒中での塩素化および酸化に安全かつ効果的な試薬であると報告されているが、有機溶媒中でのTCCAの適用は、その難溶性、ポリマーゲルの形成に起因して制限されていた。TCCAは、溶媒、例えば、THFおよびトルエンの塩素化も引き起こした。そもそもゲル含有率が高いことから、実施例4〜6と比較するための有意なデータは得られなかった。
DSV=ln(溶液のフロー時間/溶媒のフロー時間)/W2*10
%ゲル=(1−(W2*10/W1))*100
式中、W1は、最初のポリマーの重量であり、W2は、残りの重量である。
実施例14〜22において、上記で合成したポリマーの数種を、加硫ゴム組成物に用いる一般的な添加剤と配合した。表3は、混合されてゴム化合物を形成した成分を、100ゴムあたりの部数(phr)で示す。表4は、混合条件を示す。
実施例23〜26において、湿潤牽引力の改善がTgの増加のみに起因するかを判断する試験を行った。ここで、部分塩素化ポリイソプレンの市販サンプルを市販のポリイソプレン(GOODYEAR製NATSYN)と混合した。塩素化ポリイソプレンは、65重量%の塩素化を含有し、Sigma Aldrich(カタログNo.462527)から得た。塩素化および非塩素化ポリマーの両方が、DSC測定(−65℃)によって、同じTgを有すると判断された。塩素化ポリイソプレンは、n個の繰り返し単位の以下の式Vを有した。
実施例27において、攪拌機を備えた、2ガロンのN2がパージされている反応器に、1.02kgのヘキサン、3.0kgのブタジエン(ヘキサン中22.2重量%)および0.47kgのスチレン(ヘキサン中33%)を添加した。反応器に3.31mLのヘキサン中n−BuLi(1.60M)、1.63mLのヘキサン中2,2−ビス(2’−テトラヒドロフリル)プロパン(1.6M)を投入し、次いで、反応器ジャケットを60℃に加熱した。15分後、バッチ温度のピークが96℃であった。さらなる30分の後に、ポリマーセメントを、対照実施例として、ブチル化ヒドロキシトルエン(BHT)を含有するイソプロパノールにおいて凝析させてドラム乾燥した。
