Abstract >Compared with other types of polymerization, the molecular weight and its distribution (MWD) of equilibrium ring‐opening polymerization (EROP) are complicated and have not been extensively studied. By using statistic method, a series of equations based on polymerization mechanism is established to describe numbers of rings, chains, and active centers. Using this new model, the predicted results of polydimethylsiloxane synthesized by EROP agree well with experimental results. This model has advantages in molecule number, calculation speed, and stability when compared with the Monte Carlo simulation. It also has the potential to replace Monte Carlo simulation in MWD prediction. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><Abstract Type =“Main”XML：Lang =“en”> <标题类型=“main”>抽象</ title> >与其他类型的聚合相比，平衡开环聚合（EROP）的分子量及其分布（MWD）复杂，并且没有被广泛研究。通过使用统计方法，建立基于聚合机制的一系列方程来描述环，链条和活性中心的数量。使用这种新模型，通过EROP合成的聚二甲基硅氧烷的预测结果与实验结果很好。与蒙特卡罗模拟相比，该模型具有分子数，计算速度和稳定性的优点。它还具有替代MWD预测中的Monte Carlo仿真。</ p> </摘要> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-24304/'>《Macromolecular theory and simulations》</a> <b style="margin: 0 2px;">|</b><span>2017年第6期</span><b style="margin: 0 2px;">|</b><span>共7页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Long Teng&option=202" target="_blank" rel="nofollow">Long Teng;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Zhang Chen&option=202" target="_blank" rel="nofollow">Zhang Chen;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Liu Hui&option=202" target="_blank" rel="nofollow">Liu Hui;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Chen Xin&option=202" target="_blank" rel="nofollow">Chen Xin;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Zhao Shigui&option=202" target="_blank" rel="nofollow">Zhao Shigui;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Zhou Chuanjian&option=202" target="_blank" rel="nofollow">Zhou Chuanjian;</a> </p> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zkzz" style="display: none;">展开▼</span> </div> </li> <li> <div style="display: flex;"> <span class="lefttit">作者单位</span> <div style="position: relative;margin-left: 3px;max-width: 639px;"> <div class="threelineshidden zhankaihshouqi" id="fOrgthree"> <p>School of Material Science and EngineeringShandong UniversityJingshi Road 17923 Jinan 250061 China;</p> <p>School of Material Science and EngineeringShandong UniversityJingshi Road 17923 Jinan 250061 China;</p> <p>Power Sources Technology CenterState Grid Shandong Electric Power Research InstituteJinan 250100 Shandong China;</p> <p>School of Material Science and EngineeringShandong UniversityJingshi Road 17923 Jinan 250061 China;</p> <p>School of Material Science and EngineeringShandong UniversityJingshi Road 17923 Jinan 250061 China;</p> <p>School of Material Science and EngineeringShandong UniversityJingshi Road 17923 Jinan 250061 China;</p> </div> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zhdw" style="display: none;">展开▼</span> </div> </div> </li> <li > <span class="lefttit">收录信息</span> <span style="width: 86%;vertical-align: text-top;display: inline-block;"></span> </li> <li> <span class="lefttit">原文格式</span> <span>PDF</span> </li> <li> <span class="lefttit">正文语种</span> <span>eng</span> </li> <li> <span class="lefttit">中图分类</span> <span><a href="https://www.zhangqiaokeyan.com/clc/1185.html" title="高分子化学（高聚物）">高分子化学（高聚物）;</a></span> </li> <li class="antistop"> <span class="lefttit">关键词</span> <p style="width: 86%;vertical-align: text-top;"> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=cationic polymerization&option=203" rel="nofollow">cationic polymerization;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=molecular weight distribution&option=203" rel="nofollow">molecular weight distribution;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=polysiloxanes&option=203" rel="nofollow">polysiloxanes;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=ring‐opening polymerization&option=203" rel="nofollow">ring‐opening polymerization;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=simulations&option=203" rel="nofollow">simulations;</a> </p> <div class="translation"> 机译：阳离子聚合;分子量分布;聚硅氧烷;开环聚合;模拟;
