  1. 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。
  2. When the graft ratio was high, the hydrophilic side chain was long and the molecular mass of the main chain of the hydrophilic matrix was great, the diffusion of pp - g - peg in pp blends would be poor, and the diffusion coefficient would also be small

    接枝率越高、親水性側鏈的長度越長,親基體主鏈摩爾質量越大,接枝共聚物在聚丙烯共混體系中的遷移擴散性能越差,擴散系數越小。
  3. 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 。
  4. Silylate - terminated polyurethanes with built - in hydrophilic sites were synthesized. when the polymer is dispersed in water, the silane alkoxy end - groups of the polymer undergo hydrolysis, followed by condensation to form a stable cross - linked aqueous dispersion. tem studies indicated that with more incorporation of hydrophilic sites, the particle size of the dispersion decreased. it was also found that the film property depended on the particle size when the crosslinking density in particels was much higher. the average molecular weight of the elastically effective network chain mc measured by swelling experiments shows fairly good agreement with the theoretical value of mc. it was also found that the cross - linking density of the casting film may increase during the film formation and drying process

    將硅氧烷封端的含親水基團的線性聚氨酯預聚體分散於水中,獲得穩定的聚氨酯分散體.由於硅氧基團水解、縮合,在分散體粒子內產生擴鏈交聯反應,生成了交聯水基聚氨酯分散體.透射電子顯微鏡研究表明分散體粒徑小、分佈寬.掃描電子顯微鏡研究了成膜結構及成膜性能與粒徑的關系.溶脹實驗計算獲得的兩交聯點之間的平均分子量與理論平均分子量相符.研究還發現此分散體膜在乾燥過程中可進一步交聯.膜的水溶脹及機械性能表明,此分散體具有極大的工業應用價值
