Result of thermogravity analysis showed that the thermal stability of polyvinylamine chloride lowers with increasing in amination degree. Moreover, properties of dilute aqueous solutions of three types of poly chloride with different amination degree were compared by use of viscosimetric, conductometric, and potentiometric measurements. Results showed that both the electrostatic interaction of neighboring groups on the chain and the reduced viscosity of poly chloride are increased with increasing the degree of amination of poly . The equivalent conductivity is decreased with the increasing the concentration of poly chloride and increased with the increasing the amination degree of poly .
研究了聚乙烯胺盐酸盐的热稳定性和水溶液性质,发现:随着胺化度的提高,聚乙烯胺盐酸盐的对热稳定性逐步降低;聚乙烯胺盐酸盐是一种典型的聚电解质,其水溶液的pH值随平均分子量的变化并不明显,而随着聚乙烯胺胺化度的升高,pH值降低;随着聚乙烯胺盐酸盐的平均聚合度由82.3增加到201.8,它的m值(用于表征聚电解质侧链基团之间相互作用大小的常数)从5.13升高到5.58,而当聚乙烯胺盐酸盐的平均聚合度增加到311.4时,它的m值反而降低到了5.48;随着胺化度由55.65%升高到82.36%,m值由3.65提高到5.50;随着聚乙烯胺盐酸盐的平均聚合度的提高,聚乙烯胺盐酸盐的平均解离常数由7.48降低到7.26,同时随着胺化度的提高,聚乙烯胺盐酸盐的平均解离常数也由8.33降低到7.37;随着聚乙烯胺盐酸盐浓度的提高,溶液的摩尔电导率逐步降低,随着聚乙烯胺胺化度和聚合度的提高,溶液的摩尔电导率有所升高;在pH值为4左右时,聚乙烯胺盐酸盐的比浓粘度分别达到极值,而与聚合度的大小关系不大;聚乙烯胺盐酸盐的特性粘数明显高于其原料聚丙烯酰胺的特性粘数,分子量对特性粘数的影响十分明显,胺化度对特性粘数的影响并不显著。

This study was based on the soy protein isolates as raw materials. Chemical modification( acetylation,succinylation ,phosphorylation and urea modification) of SPI were used to improve adhesive strength and water resistance of SPI-based plywood adhesives. Then two modified ways combined were applied to SPI and their adhesive properties were studied. This research also characterized the thermal and adhesive properties of two major soy protein components 7S conglycinin and 11S glycinin after urea modification. Finally, the mechanism of improving SPI's adhesive properties was preliminarily discussed.

Three types of base asphalt and six SBS were used to produce SBS modified asphalt. The interaction of SBS modified asphalt was discussed in different states between the base asphalt and SBS based on their compositions. Through the traditional tests, such as penetration, soften point and ductility, and US SHRP tests, the results indicated that influences to affect the temperature susceptibility, high and low temperature performance, aging characteristics are base asphalt, SBS types and their dosages. The functions of penetration to viscosity and complex shear modulus G~* to complex dynamic shear viscosity η~* were set up, and then theviscosity-temperature susceptibility of wide temperature span and the calculation method of low temperature viscosity were obtained."Process" evaluation criterions, high grading critical temperature T_ and low grading criticaltemperature T_ , were suggested according to the high and low temperatureperformances of SBS modified asphalt. Using the experience of Repeated Creep and Recovery Test for Binders, a new high-temperature evaluation index,modification rutting factor G~*~(-9) was obtained. The results after RTFO and PAV aging indicated that traditional tests didnt differentiate base asphalt and SBS modified asphalt, but dynamic mechanics temperature spectrum and G*-5 black chart clearly reflected the influence of aging to the SBS modified asphalt. With the IR and GPC tests, the reason of aging to the SBS modified asphalt were due to asphalt phase oxygenated and SBS phase depredated.
