採用正電子湮沒技術研究了端羥基液體丁腈The synthesis technology of various liquid rubbers with different active group terminated, such as hydroxyl - terminated, carboxyl - terminated, isocyanate - terminated, ami - no - terminated, mercaptan - terminated and various main chains like polybutadiene, polyurethane, polystyrene were reviewed with 23 references
摘要綜述了端羥基、端羧基、端異氰酸酯基、端氨基、端巰基等活性端基，以及聚丁二烯、聚氨酯、聚苯乙烯等不同主鏈結構的液體橡膠的合成技術。( 2 ) the results of impact experiments show that impact strength of pf is improved and improvement lever is related to wpu ; but effect of carboxyl - terminated pu - prepolymer is better, that is to say the interpenetrating networks have priority at toughening of thermosetting resin
（ 2 ）沖擊實驗結果表明二種pu預聚物均能提高pf的沖擊強度，增韌效果與pu質量分數wpu有關；而端羧基pu能使復合物沖擊強度達到的最大值比端羥基pu稍大。( 3 ) volume shrinkage of composite decreases greatly with wpu increasing, even can arrive a negative number, but thermal stability is still good. ( 4 ) toughening mechanism is that : the formation of high molecular linear amino formate construct is the toughening reason ; hydroxyl - terminated pu - prepolymer and pf react to produce chemical bond effect which participate cure ; carboxyl - terminated pu - prepolymer and pf form semi - ipn which make toughened pf occur maximum
（ 4 ）通過紅外光譜對pf / pu共混物分子結構進行的定性分析、以及掃描電鏡對沖擊斷面形貌進行的分析，可證明聚氨酯預聚物增韌酚醛樹脂的機理是：兩個體系都是由於高分子量的線形氨基甲酸酯結構而增韌；端羥基pu與pf在共固化中產生化學鍵效應，參與pf的固化；而端羧基pu則與pf形成半互穿網路而增韌。As a result, 1 ipophilic products have the highest yield when the reaction time was 70min. the identification of ir spectrometry showed that there are more dissociated hydroxy ( ho - ) and end - groups in the liquefaction products than in the plant cellulose
經紅外光譜（ ir ）檢測結果表明，液化產物的游離羥基明顯增多，其它的游離端基也是明顯增加，這說明液化反應破壞了纖維素的晶格結構，而且部分水解了糖苷鍵。The study of in - situ construction of cytocompatible surface on pdl - la matrix via amphiphile - amino acid ( rgd ) hybrid self - segregation - the amphiphilic diblock copolymer, poly ( dl - lactide ) - poly ( ethylene oxide ) ( pla - peo ) copolymer, containing hydrophobic pla block and hydrophilic peo block was synthesized via coupling method in this dissertation. cell - adhesion - promoting amino acids and integrin receptor peptide rgd were then immobilized at the end of peo chain of pla - peo copolymer via hydroxyl group activation technique. the solvent blending and casting method was then used to obtain the amphiphile modified pdl - la membranes
兩親共聚物-氨基酸（ rgd ）雜化體原位自修飾構建聚乳酸細胞相容性表面的研究一本論文首先設計併合成了一類含疏水聚乳酸（ pla ）鏈段和親水聚氧乙烯（ peo ）鏈段的兩親嵌段共聚物材料（ pla - peo ） ，利用peo鏈端的活性官能團羥基固定了促細胞粘附的氨基酸及整合素配體多肽片段rgd 。Thiolysis hplc will be better for the dihydrochalcones which includes the compounds of xyloglucose phloretin and phloretin, the catechins and their end units. unthiolysis hplc will be better for the hydroxycinnamic acids, procyanidin b2 and catechin monomers. 2
