Abstract
Description
本願は、「FREE RADICAL INITIATOR SYSTEM AND A HIGH PRESSURE,FREERADICAL POLYMERIZATION PROCESS FOR PRODUCING A LOW DENSITY POLYETHYLENE POLYMER」と題する2007年3月9日出願の米国仮出願第60/905,999号の優先権を主張する正規の出願であり、その教示は、以下に完全に再現されるように参照によって本明細書に組み込まれる。
曇り点圧力の測定のために設計された高圧での可溶性試験を、図1に示すように高圧光学セル中で実施した。この設定では、液−固相および液−液相転移を、目視観測によって検出し、これをカメラで記録した。
セルを、成分の混合物で充填し、一定温度において0〜3500バールで加圧した。サンプルを磁気撹拌棒によって撹拌すると同時に、圧力および温度の両方をオンラインで記録した。液体の相分離挙動を、ビデオカメラを使用してリアルタイムで記録した。
開始剤
(1)Arkemaから利用可能なLuperox(登録商標)JWEB50(50重量パーセントのエチルベンゼンに溶解したポリエーテルポリ−t−ブチルペルオキシカーボネート開始剤)、ならびに
(2)Akzo Nobelから利用可能なTrigonox F(tert−ブチルペルオキシペルアセテート(「TBPA」))。
(1)n−オクタン、(2)イソ−オクタン(2,2,4−トリメチルペンタン)、(3)n−ドデカン、(4)イソ−ドデカン(2,2,4,6,6−ペンタメチルヘプタン)、および(5)Isopar(登録商標)E。
(1)イソプロパノール(2−プロパノール)および(2)アリルアルコール(1−ペンタノール)。
サンプル溶液1〜16を、表Iに列挙した配合に従って調製し、次いで上記の実験設定および実験プロトコルに従って、高圧での可溶性について実施例1〜6で試験した。結果を、以下および図2〜7に示す。
