Description
標準縣濁重合実験において、一つのバッフル、三つ羽根の攪拌機、圧力変換器、塩化ビニル(VCM)供給ライン、及び窒素パージラインを備えた、温度制御された1リットルのステンレス鋼製のBuchi反応器が、425グラムの脱イオン水、脱イオン水中の5%溶液におけるAlcotex(商標)B72(ポリビニルアセテート/アルコール)、表1及び2に示されているような量及び計量供給手順(ウォームスタート及び連続的なパーオキシドの計量供給)で充填され、そして窒素により15バールGに昇圧された。もし、漏れが観察されるなら、反応器は、実質的に全ての空気を追い出すために3回、脱気そして5バールGまで窒素で加圧される。次いで、反応器は脱気され、そしてAkzo Nobel Salt & Basics製VCMの250グラムを充填され、次いで、30〜60分間重合温度に反応器が加熱された。開始剤及び保護コロイド量及び計量供給手順がまた、表1及び2に示されている。反応器における2〜3バールの圧力降下又は反応時間の4.5時間の最初に訪れた方のいずれかの後に、重合が、開始剤及び/又は保護コロイドを計量供給することなしに更に30分間継続され、そして次いで、反応器は20〜25℃に冷却され、脱気され、そして実質的に全ての残存するVCMを取出した。ポリマーは、ろ過、洗浄、そして(流動床を使用して1時間、60℃における)乾燥後に得られた。反応器中の圧力降下までの時間は、一定圧力の時間(CPT)である。上記の実験構成を使用して、CPTにおける5分間の相違は優位性があると考えられる。
二つの開始剤、即ち、Trigonox(商標)187及びTrigonox(商標)267が使用された。夫々の個々の開始剤の計量供給手順及び重合結果は、表1及び2に示されている。
Claims (18)
- 少なくとも一つのモノマーを含む重合混合物を重合する方法において、少なくとも一つのモノマーが塩化ビニルであり、少なくとも有機開始剤及び、重合されるべきモノマーの重量に基づいて0.01〜1重量%の保護コロイドが、重合温度において重合混合物に計量供給されるところの方法。
- 保護コロイドが、ポリビニルアルコール又は40〜90%の加水分解度を持つケン化されたポリ酢酸ビニルであるところの請求項1に記載の方法。
- 有機開始剤が、重合温度において0.0001〜1時間の半減期を有するところの請求項1または2に記載の方法。
- 開始剤及び保護コロイドが同時に、少なくとも部分的に計量供給されるところの請求項1〜3のいずれか一つに記載の方法。
