聚烯烃釜内合金是一类用途广泛的高性能化通用合成树脂,采用多段序贯聚合工艺合成的聚丙烯/乙丙共聚物（PP/EPR）合金的全球年产量达上千万吨。PP/EPR釜内合金主要由乙丙无规共聚物（rEP）、多嵌段乙丙共聚物（sEP）和等规聚丙烯（iPP）三个组分构成。[1]sEP组分能增加rEP与iPP基体间的相容性,改善合金的刚性-韧性平衡特性。如何优化sEP组分的含量及其链结构已成为进一步提高PP/EPR合金性能的关键之一。另一方面,采用多区循环反应工艺（MZCR）合成的PP/EPR合金显示出更加优异的刚韧平衡特性,[2,3]对其微观机理却未有深入的认识。针对这两方面的问题,我们对国产球形负载型高效催化剂合成PP/EPR合金的规律进行了研究。在以丙烯均聚-乙丙气相共聚两段序贯反应合成PP/EP合金时,通过改变助催化剂和外给电子体,有效地调节了sEP组分的含量及其链结构,显著改善了合金的刚韧平衡特性。通过对合金链结构的详细表征,初步解释了这些效应的原因,发现增加sEP组分的丙烯嵌段长度能提高其增容效率。用单釜的周期性切换聚合实验装置模拟了MZCR合成PP/EPR合金的过程,研究了切换频率等反应参数对合金结构和性能的影响,初步掌握了MZCR工艺能进一步改善合金刚韧平衡特性的原理。

有深度和流动性良好的金融系统,加上有丰富的金融工具可抵御金融冲击,还可以增加一国金融的稳定性。但是金融发展或许存在一个边界,越过此边界进一步发展其收益或将下降。本文通过研究新兴市场发现:一、大部分新兴市场金融进一步发展仍然对经济的增长和稳定有利。二、金融发展对经济增长的促进作用是倒U型的,在越过高点之后金融深化对要素生产率的促进作用将下降。三、如果金融发展过快,快速深化的金融产业可能引发经济和金融动荡。四、提升金融稳定与金融发展之间没有太大冲突,更好的金融监管有助于提升金融稳定,促进金融发展。五、发展金融机构或金融市场不存在通用的顺序,尽管前者对经济的作用在下降而后者在上升。

The kinetic of mass loss of grades A and B of melted TNT by isothermal and non-isothermal gravimetric methods

引用

Defence technology 2018年第2期 126-131页

作者： Hamid reza Pouretedal Sajjad Damiri Parvaneh Nosrati Ehsan Forati Ghaemi Faculty of Applied Chemistry，Malek-ashtar University of Technology

The kintic and activation energy of mass loss of two grades of melted TNT explosive, grade A and grade B, with freezing points of 80.57 and 78.15 ℃, respectively, were studied by isothermal and nonisothermal gravimetric methods. In isothermal method, the mass loss of samples in containers of glass and aluminum was followed in temperatures of 80, 90 and 100 ℃. The kinetic of the mass loss of the samples in the aluminum container was higher than the kinetic of it in the glass container that can be related to the effects of heat transfer and catalytic of aluminm metal. Also, the presence of impurities in grade B was due to increasing of kinetic of mass loss of it versus grade A. The non-isothermal curves were obtained in range of 30-330 ℃ at heating rates of 10,15 and 20 ℃·*** TG/DTG data were used for determination of activation energy（Ea） of mass loss of TNT samples upon degradation by using Ozawa, Kissinger, Ozawa-Flynn-Wall（OFW） and Kissinger-Akahira-Sunose（KAS） methods as model free methods. The activation energies of grades of A and B of TNT was obtained 99-120 and 66-70 kJ mol-1respectively. The lower values of activation energy of the degradation reaction of grade B confirm the effect of impurities in the kinetics of mass loss of this grade.
