Abstract : the formation technologies, the structure and properties of tcs microporous man - made yarn - kind new polyester fibre which was spinned in tcs with some micrometallic - oxide have been studied. the results indicate that the rheological behaviour and spinnability of commixed polyester melt, and the structure and properties of the fibre, are relative to the spinning temperature, melt pressure, microporpus size for spinning, formation conditions, thermo - vascellum temperature, thermo - vascellum position and rolling speed, besides the viscosity of polyester cuts, coacervation particles, adding amount and size of micrometallic - oxide
研究表明， tcs微孔化共混聚酯熔體在成型加工中的流變行為和可紡性，及其纖維的結構性能除了與原料切片的特性粘度、凝聚粒子和共混聚酯中超細金屬氧化物微粒的添加量、粒徑等因素的影響有關外，還與紡絲溫度、紡絲熔體壓力、噴絲板微孔尺寸、冷卻成形條件、熱管溫度、熱管安裝位置以及卷繞速度等因素的影響密切有關。The rate of hydrolysis is for the most part significantly lower than the esterification rate.
多數情況下水解速度較酯化速度低得多。The experimental results further demonstrate that the combination of incompatibility polydimethylsiloxane and polyacrylate by co - vulcanization improves the both compatibility and broadens the low temperature and high temperature functional region. while in sin, to improve microphase structures and damping properties, the design to increase compatibility between two compositions and modulate crosslinking density as well as relative reaction rate of two compositions, is also effective
以上實驗結果表明，在復合橡膠阻尼材料中將聚硅氧烷與聚丙烯酸酯通過共混硫化相結合，改進了二者的相容性，拓寬了其阻尼功能區的低溫和高溫溫域；而在sin中通過改善組四川大學博士學位論文分間相容性，調節交聯密度控制其微相結構和兩種組分相對反應速度的快慢，進而控制材料阻尼性能的設計是行之有效的。This paper investigates the types of acrylic modified solvent ( methyl and dimethyl benzene ), the usage of acrylic acid, the usage of initiator, esterification time, and preliminarily tests the dehydration rate of modified demulsifier
