隨(sui)著近年來經濟的(de)不斷發展,人們對高性(xing)能(neng)環烯烴(jing)共(gong)(gong)聚物(wu)的(de)需求不斷提(ti)升(sheng)。因此開發高活性(xing)的(de)茂(mao)金屬催(cui)化(hua)劑(ji),用于(yu)催(cui)化(hua)合(he)成(cheng)環烯烴(jing)共(gong)(gong)聚物(wu),是當(dang)前人們關注的(de)重要問題。北京(jing)世(shi)紀(ji)森(sen)朗公司(si)設計生(sheng)產的(de)茂(mao)金屬化(hua)合(he)物(wu)制備(bei)反應裝置,是對雙核茂(mao)金屬化(hua)合(he)物(wu)及其制備(bei)方法和(he)應用。環烯烴(jing)共(gong)(gong)聚

隨著近年來經濟的不斷發展,人們對高性能環烯烴共聚物的需求不斷提升。因此開發高活性的茂金屬催化劑,用于催化合成環烯烴共聚物,是當前人們關注的重要問題。北京世紀森朗公司設計生產的茂金屬化合物制備反應裝置,是對雙核茂金屬化合物及其制備方法和應用。環烯烴共聚物由于具有優異的透光性和較高的熱穩定性,因此被廣泛應用于光學透鏡,醫藥包材等領域。

目前,大多數商(shang)業(ye)化(hua)(hua)(hua)(hua)的(de)(de)環(huan)(huan)烯(xi)(xi)(xi)(xi)(xi)烴(jing)(jing)(jing)(jing)共(gong)聚(ju)(ju)(ju)(ju)(ju)(ju)(ju)物(wu)(wu)(wu)(wu)(wu)產品,主(zhu)(zhu)要由(you)α烯(xi)(xi)(xi)(xi)(xi)烴(jing)(jing)(jing)(jing)與(yu)環(huan)(huan)烯(xi)(xi)(xi)(xi)(xi)烴(jing)(jing)(jing)(jing)共(gong)聚(ju)(ju)(ju)(ju)(ju)(ju)(ju)而得。根據研(yan)究(jiu)發現,環(huan)(huan)烯(xi)(xi)(xi)(xi)(xi)烴(jing)(jing)(jing)(jing)共(gong)聚(ju)(ju)(ju)(ju)(ju)(ju)(ju)物(wu)(wu)(wu)(wu)(wu)所具有(you)的(de)(de)高(gao)(gao)(gao)透光率和高(gao)(gao)(gao)耐(nai)熱(re)(re)(re)性(xing)(xing)(xing),與(yu)聚(ju)(ju)(ju)(ju)(ju)(ju)(ju)合(he)(he)物(wu)(wu)(wu)(wu)(wu)主(zhu)(zhu)鏈中(zhong)(zhong)環(huan)(huan)烯(xi)(xi)(xi)(xi)(xi)烴(jing)(jing)(jing)(jing)結(jie)構單(dan)元的(de)(de)比(bi)例(li)有(you)直接關系。當環(huan)(huan)烯(xi)(xi)(xi)(xi)(xi)烴(jing)(jing)(jing)(jing)結(jie)構單(dan)元的(de)(de)比(bi)例(li)降低(di)(di)(di)時(shi),聚(ju)(ju)(ju)(ju)(ju)(ju)(ju)合(he)(he)物(wu)(wu)(wu)(wu)(wu)的(de)(de)耐(nai)熱(re)(re)(re)性(xing)(xing)(xing)變(bian)(bian)弱,玻(bo)璃(li)化(hua)(hua)(hua)(hua)轉(zhuan)變(bian)(bian)溫(wen)度降低(di)(di)(di)。反之,則(ze)聚(ju)(ju)(ju)(ju)(ju)(ju)(ju)合(he)(he)物(wu)(wu)(wu)(wu)(wu)的(de)(de)耐(nai)熱(re)(re)(re)性(xing)(xing)(xing)增(zeng)(zeng)強(qiang)。另一方面(mian),隨(sui)著環(huan)(huan)烯(xi)(xi)(xi)(xi)(xi)烴(jing)(jing)(jing)(jing)結(jie)構單(dan)元比(bi)例(li)的(de)(de)降低(di)(di)(di),α烯(xi)(xi)(xi)(xi)(xi)烴(jing)(jing)(jing)(jing)鏈段的(de)(de)長度將(jiang)逐漸增(zeng)(zeng)加,此(ci)時(shi)聚(ju)(ju)(ju)(ju)(ju)(ju)(ju)合(he)(he)物(wu)(wu)(wu)(wu)(wu)中(zhong)(zhong)將(jiang)會出現部分聚(ju)(ju)(ju)(ju)(ju)(ju)(ju)合(he)(he)物(wu)(wu)(wu)(wu)(wu)結(jie)晶,導致聚(ju)(ju)(ju)(ju)(ju)(ju)(ju)合(he)(he)物(wu)(wu)(wu)(wu)(wu)的(de)(de)透光率大幅降低(di)(di)(di),霧度提高(gao)(gao)(gao),影響(xiang)了環(huan)(huan)烯(xi)(xi)(xi)(xi)(xi)烴(jing)(jing)(jing)(jing)共(gong)聚(ju)(ju)(ju)(ju)(ju)(ju)(ju)物(wu)(wu)(wu)(wu)(wu)在光學(xue)材料中(zhong)(zhong)的(de)(de)應(ying)(ying)用(yong)。因此(ci),適(shi)當提高(gao)(gao)(gao)環(huan)(huan)烯(xi)(xi)(xi)(xi)(xi)烴(jing)(jing)(jing)(jing)共(gong)聚(ju)(ju)(ju)(ju)(ju)(ju)(ju)物(wu)(wu)(wu)(wu)(wu)中(zhong)(zhong)環(huan)(huan)烯(xi)(xi)(xi)(xi)(xi)烴(jing)(jing)(jing)(jing)單(dan)元的(de)(de)比(bi)例(li),是維(wei)持(chi)環(huan)(huan)烯(xi)(xi)(xi)(xi)(xi)烴(jing)(jing)(jing)(jing)共(gong)聚(ju)(ju)(ju)(ju)(ju)(ju)(ju)物(wu)(wu)(wu)(wu)(wu)優異性(xing)(xing)(xing)能的(de)(de)關鍵所在。用(yong)于催(cui)(cui)(cui)化(hua)(hua)(hua)(hua)α烯(xi)(xi)(xi)(xi)(xi)烴(jing)(jing)(jing)(jing)與(yu)環(huan)(huan)烯(xi)(xi)(xi)(xi)(xi)烴(jing)(jing)(jing)(jing)共(gong)聚(ju)(ju)(ju)(ju)(ju)(ju)(ju)的(de)(de)催(cui)(cui)(cui)化(hua)(hua)(hua)(hua)劑(ji)包括了ZieglerNatta催(cui)(cui)(cui)化(hua)(hua)(hua)(hua)劑(ji),茂(mao)金(jin)(jin)屬(shu)催(cui)(cui)(cui)化(hua)(hua)(hua)(hua)劑(ji)以及后過渡金(jin)(jin)屬(shu)催(cui)(cui)(cui)化(hua)(hua)(hua)(hua)劑(ji)等(deng)。其(qi)中(zhong)(zhong)茂(mao)金(jin)(jin)屬(shu)催(cui)(cui)(cui)化(hua)(hua)(hua)(hua)劑(ji)由(you)于具有(you)催(cui)(cui)(cui)化(hua)(hua)(hua)(hua)活(huo)性(xing)(xing)(xing)高(gao)(gao)(gao),且具有(you)單(dan)活(huo)性(xing)(xing)(xing)中(zhong)(zhong)心,可有(you)效催(cui)(cui)(cui)化(hua)(hua)(hua)(hua)合(he)(he)成(cheng)相對分子(zi)量分布窄、組(zu)成(cheng)分布均勻(yun)的(de)(de)烯(xi)(xi)(xi)(xi)(xi)烴(jing)(jing)(jing)(jing)共(gong)聚(ju)(ju)(ju)(ju)(ju)(ju)(ju)物(wu)(wu)(wu)(wu)(wu)等(deng)特點,因此(ci)作為(wei)催(cui)(cui)(cui)化(hua)(hua)(hua)(hua)α烯(xi)(xi)(xi)(xi)(xi)烴(jing)(jing)(jing)(jing)與(yu)環(huan)(huan)烯(xi)(xi)(xi)(xi)(xi)烴(jing)(jing)(jing)(jing)共(gong)聚(ju)(ju)(ju)(ju)(ju)(ju)(ju)的(de)(de)首選催(cui)(cui)(cui)化(hua)(hua)(hua)(hua)劑(ji)。可用(yong)于環(huan)(huan)烯(xi)(xi)(xi)(xi)(xi)烴(jing)(jing)(jing)(jing)共(gong)聚(ju)(ju)(ju)(ju)(ju)(ju)(ju)物(wu)(wu)(wu)(wu)(wu)合(he)(he)成(cheng)的(de)(de)報(bao)道中(zhong)(zhong),用(yong)于催(cui)(cui)(cui)化(hua)(hua)(hua)(hua)聚(ju)(ju)(ju)(ju)(ju)(ju)(ju)合(he)(he)的(de)(de)茂(mao)金(jin)(jin)屬(shu)催(cui)(cui)(cui)化(hua)(hua)(hua)(hua)劑(ji)普(pu)遍為(wei)單(dan)核茂(mao)金(jin)(jin)屬(shu)催(cui)(cui)(cui)化(hua)(hua)(hua)(hua)劑(ji)。同時(shi),不少(shao)茂(mao)金(jin)(jin)屬(shu)催(cui)(cui)(cui)化(hua)(hua)(hua)(hua)劑(ji)在催(cui)(cui)(cui)化(hua)(hua)(hua)(hua)α烯(xi)(xi)(xi)(xi)(xi)烴(jing)(jing)(jing)(jing)與(yu)環(huan)(huan)烯(xi)(xi)(xi)(xi)(xi)烴(jing)(jing)(jing)(jing)共(gong)聚(ju)(ju)(ju)(ju)(ju)(ju)(ju)合(he)(he)實(shi)驗中(zhong)(zhong),仍然(ran)存在催(cui)(cui)(cui)化(hua)(hua)(hua)(hua)活(huo)性(xing)(xing)(xing)低(di)(di)(di),環(huan)(huan)烯(xi)(xi)(xi)(xi)(xi)烴(jing)(jing)(jing)(jing)單(dan)體插(cha)入率低(di)(di)(di),所得聚(ju)(ju)(ju)(ju)(ju)(ju)(ju)合(he)(he)物(wu)(wu)(wu)(wu)(wu)玻(bo)璃(li)化(hua)(hua)(hua)(hua)轉(zhuan)變(bian)(bian)溫(wen)度低(di)(di)(di)等(deng)問題,限制了聚(ju)(ju)(ju)(ju)(ju)(ju)(ju)合(he)(he)物(wu)(wu)(wu)(wu)(wu)的(de)(de)應(ying)(ying)用(yong)范圍。
