The activities of peroxidases and superoxide dismutase increased dramatically 2 h after being treated by avermectin dilutions which were added with copper abietate, 1427 and 412103. This implied that the three adjuvants had higher permeabilities on P. xylostella larvae.

Results of test showed that DFA-PEG polyester and its derivant had excellentemulsification performance, and emulsion was exquisite and steady, the surfacetension and critical micelle concentration of DFA-PEG polyester and sulfatedDFA-PEG polyester were very low, DFA-PEG polyester terminated with rosin acid hadcertain antifoaming performance, but surface tension and CMC increase to extent.

性能测试表明，DFA-PEG聚酯及其两种衍生物均具有优良的乳化性能，乳液细腻且稳定；DFA-PEG聚酯及其硫酸酯盐水溶液的表面张力和临界胶束浓度较低：DFA-PEG聚酯松香酸酯还具有一定的抑泡性能，与DFA-PEG聚酯及其硫酸酯盐比，其水溶液表面张力和临界胶束浓度有所增加。

The effects of d isproportionated potassium rosinate on the polymerization of cold ESBR and the stability of the latex were studied.

In this paper, firstly using natural fatty acids including lauric acid, myristic acid, palmitic acid etc. and disproportionated rosin as starting materials, the acyl reaction of starting materials with SOCl_2 respectively, and then using Schotten-Baumann condensation: on the reaction conditions of alkalescence, condensation of acylchloride with amino acid (sarcosine, glycine, alanine etc.), and then acidification, saltation. A series of anionic surfactants of N-acyl amino: sodium N-fatty acyl sarcosinate (SFS-12, SFS-14, SFS-16); sodiun N-fatty acyl glycinate(SFG-12, SFG-14, SFG-16); sodium N-fatty acyl alaninate(SFA-12, SFA-14, SFA-16)and sodium N-disproportionated rosinoyl aminatewere prepared. During the preparation of N-acylamino acid, the reaction conditions of acylchloride with amino acid condensation were identified by optimizing the synthetic conditions of N-lauroyl sarcosine: mol ratio of amino acid to acylchloride 2:1, reaction taken place in a solvent composed by acetone/water 2:1, acylchloride and 20% NaOH were slowly added to the reaction mixture at the same time while maintaining the pH at 9~10, after completion of adding maintaining reacting for 2.5h at 25℃.

首先以月桂酸、肉豆蔻酸、棕榈酸等天然脂肪酸和歧化松香为原料，与氯化亚砜反应制得酰氯，然后采用Schotten-Baumann 缩合法路线，即在碱性条件下，酰氯和氨基酸(肌氨酸、甘氨酸、丙氨酸等)缩合，经过酸化、成盐，合成一系列氨基酸型阴离子表面活性剂：脂肪酰肌氨酸钠，即月桂酰肌氨酸钠(SFS-12)、肉豆蔻酰肌氨酸钠(SFS-14)、棕榈酰肌氨酸钠(SFS-16)；脂肪酰甘氨酸钠，即月桂酰甘氨酸钠(SFG-12)、肉豆蔻酰甘氨酸钠(SFG-14)、棕榈酰甘氨酸钠(SFG-16)；脂肪酰丙氨酸钠，即月桂酰丙氨酸钠(SFA-12)、肉豆蔻酰丙氨酸钠(SFA-14)、棕榈酰丙氨酸钠(SFA-16)；N-歧化松香酰基氨基酸钠(sodium N-disproportionated rosinoyl aminate)，即N-歧化松香酰基肌氨酸钠(sodium N-disproportionated rosinoyl sarcosinate ，简称SDRS)、N-歧化松香酰基甘氨酸钠(sodium N-disproportionated rosinoyl glycinate，简称SDRG)、N-歧化松香酰基丙氨酸钠(sodium N-disproportionated rosinoyl alaninate，简称SDRA)。

Thirdly, the acrylic rosin was synthesized by the addition reaction from gum rosin andacrylic acid. The levo-pimaric acid was converted into acrylic pimarie acid throughDiels-Alder addition with acrylic acid. The abietic-type acids in the gum rosin were inisomerization balance under high temperature, and the abietic acid and palstric acid would beconverted into levo-pimaric acid and reacted in the later type.

第三，通过脂松香与丙烯酸加成合成了丙烯酸松香，该反应是左旋海松酸与丙烯酸发生Diels-Alder加成反应生成丙烯海松酸，由于脂松香中的枞酸型树脂酸在高温下处于异构化平衡状态，因此随着反应的进行枞酸、长叶松酸等会异构化为左旋海松酸参与反应。
