L^(-1) 2 mL. The graft copolymer's thermolysis tempreture reached 389℃ by DSC analysis, it improves 48℃ compared with the LV-PAC. It was illustrated that the heat-resistance of LV-PAC could be effectively improved by grafting sulphonate.

DSC分析表明接枝后所得共聚物的热分解温度达到了389℃，比LV-PAC提高了48℃，说明通过接枝磺酸盐的方法可以有效地提高LV-PAC的耐热稳定性。

The existing form of boron on the rubbing surfaces is sodium metaborate which can be dissolved in water. The hydration water of so- dium metaborate can reduce the aiitiwear function on Four-ball Machine but enhance its antiwear ability on Timken Tester. The study also revealed that sulfonate dispersant Can reduce the antiwear function of sodium metaborate while succinimide dispersant enhance its antiwear ability.

结果表明，含偏硼酸钠的白油能在摩擦表面形成含偏硼酸钠的表面膜而具有较好的抗磨性，硼在摩擦表面膜中以偏硼酸钠的形式存在，钠和钙的石油磺酸盐型分散剂会降低偏硼酸钠的抗磨性，而丁二酰亚胺类分散剂则能提高其抗磨性。

The method comprises melt extruding a mixture comprising a polyester and one or more alkyl metal sulfonates where the metal is Na, Li or K and the alkyl is straight or branched chain alkyl of 12 to 15 carbon atoms, or is straight or branched chain alkenyl of 12 to 18 carbon atoms.

方法包括将包括聚酯和一种或多种烷基金属磺酸盐的混合物熔体挤出，其中金属是Na、Li或K和烷基是12-15个碳原子的直链或支链烷基，或是12-18个碳原子的直链或支链链烯基。

In this paper the pulping of wheat straw with Na〓SO〓, HCHO and AQ was studied. The objectives of this study are to increase pulp yields, physical strength and bleachability and to produce lignosulfonate which has excellent solubilities and surface activities.
