Abstract
Description
A.実施例エラストマーA−D(カルボキシラートで停止したゴム)
実施例エラストマーA
二つの50ガロン反応器を利用した。第一の反応器にヘキサンを投入し、反応器ジャケットを用いて該反応器を210°Fに加熱した。次に、ヘキサン(供給速度51.99lbs/hr)、1,3-ブタジエン(ヘキサン中22%)(供給速度227.27lbs/時間)、オリゴマー状オキサラニルプロパン(OOPs)(0.020lbs/hr、ヘキサン中15%、シリンジポンプ)及びゲル化抑制剤(1,2-ブタジエン、ヘキサン中5%)(供給速度0.125lbs/hr)を第一反応器に連続して投入した。該反応器に、n-ブチルリチウムの供給(2.2lbs/hr、ヘキサン中3%)と共にヘキサンの第二供給(供給速度33.24lbs/hr)を投入した。反応が進むにつれて、ジャケット温度を175°Fに低下させ、反応器の最上部を約200°Fの最高温度に保った。反応器の滞留時間は約51分であった。ポリブタジエン生成物を第一反応器の最上部から移して第二反応器中に供給した。これは、48,000の基礎Mnをもたらした。カップリング後に測定したMnは、表1中に報告されるように増大した。第二反応器に、約0.2lbs/時間の速度でCO2を加えて、ポリブタジエンをカップリングして停止させ、カルボキシラートで停止したエラストマーを得た。また、第二反応器の滞留時間は、約51分であった。
実施例Bについては、n-ブチルリチウムの供給速度を第一供給で2.0lbs/hrとした以外は、実施例Aに記載されたものと同一の方法を行った。CO2供給速度は、実施例Aの場合と同一であった。これは、基礎Mnが約51,600の重合体を得た。
実施例Cについては、n-ブチルリチウムの供給速度を第一供給で1.8lbs/hrとし、CO2供給速度を約0.1lbs/hrとした以外は、実施例Aに記載されたものと同一の方法を行った。これは、基礎Mnが約60,400の重合体を得た。
実施例Dについては、n-ブチルリチウムの供給速度を第一供給で1.5lbs/hrとし、CO2供給速度を約0.1lbs/hrとした以外は、実施例Aに記載されたものと同一の方法を行った。これは、基礎Mnが約70,000の重合体を得た。
比較例A
比較例Aのカルボキシラートで停止しないポリブタジエンについては、ファイヤーストーンポリマーズ社(アクロン、オハイオ州)にてDiene(登録商標)55の商標名で販売されている市販のポリブタジエンを利用した。(二種類のDiene 55、AC−10及びAC−15が利用でき、比較例の目的で交換できるように使用され得る。)Diene(登録商標)55の特性を上記表1に示す。
CO2の代わりにジオクチルテレフタラートを27.71ml/hrの速度で加えた以外は、実施例エラストマーAに記載の方法に従って、カルボキシラートで停止されないポリブタジエンを調製した。
予め調製されたカルボキシラートで停止したエラストマー(実施例A−D)と上記カルボキシラートで停止されないエラストマー(比較例A及びB)とを利用し、該エラストマーの耐衝撃性改質プラスチックとの様々なブレンドを調製した。表2は、例に用いたエラストマーとイオノライザーとの様々な組み合わせを示す。該例の目的で、調製した耐衝撃性改質プラスチックはHIPSであった。耐衝撃性改質プラスチックとしてのHIPSの使用に対して本開示又は特許請求の範囲を限定するように、それらの例を決して解釈すべきでない。様々な他の耐衝撃性改質プラスチックがよく知られており、ここに開示されたカルボキシラートで停止したエラストマーとのブレンドを調製する手段は、当業者の知識の範囲内である。
エラストマー(ゴム)48〜64グラム
スチレン(溶媒)736〜752グラム
エチルベンゼン(追加の溶媒)141.2グラム
鉱物油20グラム
I−1076(Irganox 1076酸化防止剤、チバ社)8.4グラム−10%ヘキサン溶液で加えられた
三級ブチルベンゾアート(開始剤)0.15グラム
様々なHIPS組成物(例1〜28)を分析し、それらの特性を決定した。以下、結果を表4−1及び4−2に報告する。
