長鏈帶電的合成聚合物和天然聚合物,能夠在膠體間搭橋而使膠體不穩定。A kind of novel pu and poly ( acrylate - co - methyl methacrylate ) s with nonlinear optical conjugated group were synthesized. their properties were studied. the main contents of this dissertation consist of the following points : 1
本論文合成了一類含非線性生色團的長側鏈的聚氨酯和一類聚丙烯酸酯及其與甲基丙烯酸甲酯的共聚物,並對它們的非線性光學性能進行了研究。Polymers are most commonly formed by two main types of growth reaction traditionally referred to us condensation (step reaction) and addition (chain reaction) processes.
形成聚合物的最普通方式是靠兩種主要的增長反應,習慣上分別稱做縮合(逐步反應)過程和加成(鏈式反應)過程。These glycosaminoglycan ( gag ) chains are long, linear carbohydrate polymers that are negatively charged under physiological conditions, due to the occurrence of sulphate and uronic acid groups
這些粘多糖( gag )鏈是長條線狀的碳水化合物聚合體,在正常生環境下,由於硫酸根和糖醛酸根的存在而處于負電位。Poly ( ethylene glycol ) ( peg ) is a hydrophilic polymer which has flexible long chain
摘要聚乙二醇是一類親水性長鏈聚合物。The long polymers, in contrast, are generally poor conductors in their pure state
相比之下,單純的長鏈聚合物通常是很差的導體。Standard rubber bands, which can stretch up to several hundred percent then snap back into shape, are made from long chains of cross - linked polymers
標準橡皮筋由交錯連接的長鏈聚合物製成,能拉伸至原先長度的幾倍,釋放后可縮回原型。The urea - formaldehyde ( uf ) polymer / sio2 composite microspheres were prepared by polymerization - induced colloid aggregation ( pica ) method. the formation mechanism of composite microspheres is attributed to the fact that that urea and formaldehyde firstly undergo acid - catalyzed polymerization to form oligomers, and then the sol particles are adsorbed on the chain of oligomers by wan der walls force and hydrogen bonding. when the oligomers reach the critical chain length, they separate from solution due to phase separation
對復合微球形成機理的研究表明,尿素和甲醛在酸性條件下自身聚合可以形成高分子微球,在sio _ 2酸性溶膠中發生聚和反應時,隨著反應的進行,齊聚物不斷生成, sio _ 2膠體顆粒逐漸吸附在齊聚物分子鏈上,當聚合物鏈達到沉澱臨界鏈長時,由於相分離作用,從前驅物溶液中析出,同時sio _ 2膠體顆粒均勻的分佈在脲醛聚合物網路中,隨之沉澱出來,形成脲醛sio _ 2復合微球。One is made out of small organic molecules, the other out of long, conjugated polymer molecules
一類是由有機小分子組成,另一類則是由長鏈狀的共軛聚合物分子製造的。The length of the polymer chain is specified by the number of repeat units in the chain. this is called the degree of polymerization
聚合物鏈的長度可以用鏈中重復單元數來表示,叫做聚合度。As the tender part of polymer molecule, the poly ( propylene glycol ) ( ppg ) was studied. the result suggested that prepolymer which was prepared with the ppg ( molecular weight is 1000 ) has good capability. it ' s uv - curing velocity is 35m / min, glossiness is 139. 3 %, tensibility is 23. 88 % and tensile strength is 4. 475mpa
