  inducing graft
The small bowel is unique among vascularized organ grafts because it not only elicits a vigorous rejection reaction but is also capable of inducing graft-versus-host disease (GVHD).
      
The blocking of DC co-stimulation properties may therefore offer a means of inducing graft tolerance.
      


By the direct radiation grafting techonique, kinetics of the Gamma-induced graft copolymerization of st-AA to polytetrafluoroethyene has been studied at 20°-40℃. Dependence of the grafting temperature on the critical radiation intensity has been found. Above a given critical radiation intensity, the grafting is limited to the surface. Below that intensity, the grafting proceeds in the mass. Optical microscope and scanning electron microscope were used to study the structure of the cross section and surface...

By the direct radiation grafting techonique, kinetics of the Gamma-induced graft copolymerization of st-AA to polytetrafluoroethyene has been studied at 20°-40℃. Dependence of the grafting temperature on the critical radiation intensity has been found. Above a given critical radiation intensity, the grafting is limited to the surface. Below that intensity, the grafting proceeds in the mass. Optical microscope and scanning electron microscope were used to study the structure of the cross section and surface of the grafted film. The grafted amount of the surface grafted film is about 1 mg/cm2, thus, the average adhesive strength is found to be above 100 kg/cm2. The electrical properties of the surface grafted film are the same as those in nongraft film. This indicates that the Gamma radiation-induced surface graft copolymer of at-AA to polytetrafluoroethyene could be used as constructional material with strong adhesive strength or as adhesive sealing material of the electronic parts.

本文采用共辐照工艺,在20°—40℃范围内研究了聚四氟乙烯辐射引发接枝苯乙烯-丙烯酸的动力学。找到了接枝温度与临界辐照强度的关系。高于临界辐照强度,接枝发生在表面,反之,接枝发生在整体。借光学显微镜和扫描电子显微镜研究了接枝膜的断面和表面结构。表面接枝膜的接枝量约1毫克/厘米~2,平均粘结强度高达100公斤/厘米~2以上。表面接枝膜的电性能与未接枝的聚四氟乙烯相仿。可知聚四氟乙烯表面辐射接枝苯乙烯-丙烯酸可用作强粘结强度的结构材料或电子元件的粘结密封材料。

Radiation-Induced graft Copolymerization is one of the importantmethods in modifaction of the natura1 polymer materials. This paper reports the radiation-induced graft Copolymerization of n-butyl acrylate onto Chrome-tanned skin by ~(60)Co γ-ray and its filling effect. The produced samples and its residue of acid hydrolysis were measured to dtterminethe content of nitrogen element, the IR spectra and the Ninhydrin colour test. The resultsindicate that the real graft copolymeriazation of hide collagen with n-butyl acrylate takesplace during the radiation. It is shown from our experiment results that the percentage of grafting increases withincreasing dose and the concentration of monomer. Good filling effect can also be achivedin the radiation-induced graft copolymerization of n-butyl acrylate onto chrome-tannedskin

辐射引发接技共聚是一种重要的改性天然高分子材料的方法。本文报道了在~(60)Coγ射线辐照下,引发铬鞣皮与丙烯酸正丁酯的接枝共聚反应及其对皮革的填充作用。 通过对反应物及其酸水解残余物进行氮含量的测定,红外光谱分析及茚三酮显色试验,证实了皮胶原与丙烯酸正丁酯发生了接枝共聚反应。试验结果表明,接枝率随单体浓度与辐照剂量的增加而增加。辐照接枝后,确有填充效果。

The palladium- grafting polymers has been investigated by X-ray photoelectronspectroscopy (XPS). It is indicated that peak width of C_(1s) and O_(1s) spectra of MgO-g-PAN-Pd (radiation-induced graft) is more than that of MgO-PAN-Pd (chemicalgraft) and peak numbers of former are one more than later. According to report in reference, this peak...

Polymer bound palladium complex catalyst with grafting acryloni-trile on inorganic compound (MgO, Y-molecular sieve silica) by pre-radiation me-thod were studied. The palladium- grafting polymers has been investigated by X-ray photoelectronspectroscopy (XPS). It is indicated that peak width of C_(1s) and O_(1s) spectra of MgO-g-PAN-Pd (radiation-induced graft) is more than that of MgO-PAN-Pd (chemicalgraft) and peak numbers of former are one more than later. According to report in reference, this peak is attributed to-O-C-group.Thus,the graft acrylonitrile on MgO may complete through oxygen atoms in MgO andβ-carbon atoms in acrylonitrile. Polymer catalyst obtained by radiation grafting is ahigher active hydrogenation catalyst for olefines and better antitoxic than that ofone obtained by chemical method. and it has selectivity for bydrogenation catalyst.

本文采用预辐照接枝工艺研究了在无机物(氧化镁、Y型分子筛、二氧化硅等)上接枝丙烯腈,并以此为配位体的钯络合物高分子催化剂。X线光电子能谱(XPS)的研究结果表明,MgO-g-PAN-Pd(辐射接枝法)的C_(12)和O_(1?)窄谱比Mg—PAN—Pd(化学聚合法)变宽,而且多一个峰。据文献报导,该峰应归于—O—C—集团,因此MgO与丙烯腈的辐射接枝,可能是在MgO中的氧原子与丙烯腈中的β-碳原子之间进行的。用辐射接枝得到的高分子催化剂对烯烃的加氢活性和抗毒性均比用化学法担载在无机物表面上的聚丙烯腈—钯络合物催化剂要好些,而且对不同的烯烃催化加氢有一定的选择性。
