摘要:
<正>合成了一种烯基琥珀酸酐(ASA)新型乳化剂P—DAVM。P—DAVM具有嵌段结构,并具有显著的疏水缔合性质和表面活性。ASA/P—DAVM乳状液的黏度分析表明甲基丙烯酸正丁酯(MBA)的较佳质量分数为2.00%;稳定性分析表明在聚合物中引入MBA可大大提高ASA乳状液的稳定性,采用P-DAVM乳化的ASA乳状液在室温和密闭条件下可以稳定存放24h。手抄片施胶试验结果表明,ASA与P-DAVM较适宜的质量比为1:1,ASA加入量为0.10%时,手抄片的Cobb60值可以达到24.75g/m2,满足普通书写用纸的施胶要求。
Abstract:
The natural distributing populations of the indigenous timber species Cordia afiicana that grew in and around the area of Mizan Teferi in Ethiopia were investigated. Bulk seed samples were selected from ten phenotypically superior trees in different natural populations. They were evaluated through the performance of their half-sibs and especially examined for variability in seed morphometrics, seed germination, and seedling growth at nursery stage. The results showed that there was no correlativity between germination percentage and seedling height, but there were significant differences among provenances in all studied attributes. The elite trees for establishing seed orchard were screened out in pilot study. The observed variability of this species would have applications in could be used to geneticresources conservation and tree improvement. The germplasm supplied from nurseries and germplasm availability enhance the protection and utilization of natural regeneration,on farm.
