Description
上記したように不飽和結合を分子内に有する化合物にて末端変性したものは、式(a1)で表わされる構造単位の他に、末端の不飽和結合含有構造単位(a2)もビニル基を有するので、両者の合計のモル分率(a3)が、0.10〜0.50であることがよい。
多官能ビニル共重合体は分子量に分布を持つ重合体であり、当然、その慣性半径も分布を有しているため、重量平均分子量における慣性半径を全体の慣性半径の平均値として採用するものである。

残存スチレンモノマー及び重合溶媒は、脱揮工程の構成及び脱揮工程の運転条件により、低減することができ、二段脱揮或いは二段注水脱揮などの構成とすることで好ましい範囲に調整することができる。
メタノール可溶分(質量%)=(P−N)/P×100
ジビニルベンゼン3.1モル(399.4g)、エチルビニルベンゼン0.7モル(95.1g)、スチレン0.3モル(31.6g)、2−フェノキシエチルメタクリレート2.3モル(463.5g)、トルエン974.3gを3.0Lの反応器内に投入し、50℃で42.6gの三フッ化ホウ素ジエチルエーテル錯体を添加し、6.5時間反応させた。重合反応を炭酸水素ナトリウム溶液で停止させた後、純水で3回油層を洗浄し、室温で反応混合液を大量のメタノールに投入し、重合体を析出させた。得られた重合体をメタノールで洗浄し、濾別、乾燥、秤量して、多官能ビニル共重合体A372.5gを得た。この多官能ビニル共重合体Aの重量平均分子量Mwは8000で、ジビニル化合物由来のビニル基を含有する構造単位(a1)のモル分率は0.44、末端の2−フェノキシエチルメタクリレート由来の二重結合(a2)は0.03、両者を合わせた合計のモル分率(a3)は0.47であった。また重量平均分子量8000における共重合体の慣性半径は6.4nmであった。本共重合体の二重結合のモル分率と慣性半径の比は13.6であり、かつ、直鎖型の分子量8000における慣性半径が15nmであることと比較すると本合成例における多官能ビニル共重合体は分岐構造をとっていることがわかる。
(スチレン系樹脂組成物PS−1〜PS−12の製造)
完全混合型撹拌槽である第1反応器と第2反応器及び静的混合器付プラグフロー型反応器である第3反応器を直列に接続して重合工程を構成した。各反応器の容量は、第1反応器を39L、第2反応器を39L、第3反応器を16Lとした。表1に記載の原料組成にて、原料溶液を作成し、第1反応器に原料溶液を表1に記載の流量にて連続的に供給した。重合開始剤は、第1反応器の入口で表1に記載の添加濃度(原料スチレンに対する質量基準の濃度)となるように原料溶液に添加し、均一混合した。架橋剤及び連鎖移動剤は、表1に示すように第1反応器の入口で表1に記載の添加濃度(原料スチレンに対する質量基準の濃度)となるように添加し、均一混合した。架橋剤としては、合成例で得た多官能ビニル共重合体A又はジビニルベンゼン(DVB)を使用した。また、表1に記載の重合開始剤は次の通りで、連鎖移動剤としてt−ドデシルメルカプタンを用いた。
重合開始剤−1 :1,1−ジ(t−ブチルパーオキシ)シクロヘキサン(日油株式会社製パーヘキサC)
重合開始剤−2 :2,2−ジ(4,4−t−ブチルパーオキシシクロヘキシル)プロパン(日油株式会社製パーテトラA)
なお、第3反応器では、流れの方向に沿って温度勾配をつけ、中間部分、出口部分で表1の温度となるよう調整した。
続いて、第3反応器より連続的に取り出した重合体を含む溶液を直列に2段より構成される予熱器付き真空脱揮槽に導入し、表1に記載の樹脂温度となるよう予熱器の温度を調整し、表1に記載の圧力に調整することで、未反応スチレン及びエチルベンゼンを分離した後、多孔ダイよりストランド状に押し出しして、コールドカット方式にて、ストランドを冷却および切断しペレット化した。なお、PS−1〜4は実施例であり、PS−5〜12は比較例である。実施例のペレットは、板状押出発泡体用のスチレン系樹脂組成物のペレットである。
また、各反応器出口とペレットの分子量Mw、Mzより、本発明の多官能ビニル共重合体を用いることで、重合初期より高分岐型超高分子量共重合体が効率良く生成していることがわかる。
また、同時に次の基準に従い発泡性の判定を行った。
○:気泡のサイズが均一で独立している。
△:気泡のサイズがやや不均一で、一部連続した気泡が存在する。
×:気泡のサイズが不均一で、一部連続した気泡がやや多く存在する。
スチレン系樹脂組成物100質量部に対して、ヘキサブロモシクロドデカン4質量部、発泡核剤としてタルクを0.5質量部添加した後ブレンドし、得られた混合物を40mm径の単軸押出機(シリンダー温度200℃)に供給し、溶融混合した後、発泡剤としてブタンガス5質量部を圧入した。その後、65mm径の単軸押出機に移送し、出口の樹脂温度が120℃となるよう冷却し、押出機の先端に厚さ方向2mm、幅方向400mmの長方形断面のスリットを有するダイより押出して、厚さ50mm、幅500mmの板状の発泡体を製造した。それぞれの組成物について、表2の発泡体密度及び気泡径となるよう、発泡剤量や発泡核剤の量を調整した。得られた発泡体の発泡性、圧縮強度を表2に示す。
