通过在玻璃表面接枝聚乙烯链来改善玻璃与聚乙烯(高密度聚乙烯(HDPE)或低密度聚乙烯(LDPE))之间的附着力。合成了不同摩尔质量的端氯硅烷封端聚乙烯(PE)，以获得(I)能或不能与聚乙烯基质的自由链结晶的半结晶聚合物和(Ii)能与玻璃表面的硅醇基反应的聚合物链。考虑了烷基氯硅烷(烷基链长从C4H9到C30H61)的接枝，并与聚合物链进行了比较。研究了接枝在玻璃表面的官能化聚乙烯的摩尔质量对聚乙烯/玻璃界面粘附性的影响。为此，采用非对称双悬臂梁试验来确定界面的断裂能GI。在高密度和低密度聚乙烯/玻璃接头上，界面的断裂能都是不同的.
The adhesion between glass and polyethylene (high-density polyethylene (HDPE) or low-density polyethylene (LDPE)) was improved by means of polyethylene chains grafted on the glass surface. Chlorosilane-terminated polyethylene (PE) with different molar masses were synthesized in order to obtain (i) semicrystalline polymers able or not to crystallize with the free chains of the polyethylenes matrices and ( ii) polymer chains which could react with the silanol groups from the glass surface. The grafting of alkylchlorosilanes (alkyl chain length varying from C4H9 to C30H61) was considered in comparison to the polymer chains. The adhesion developed at the polyethylene/glass interface was studied as a function of the molar mass of functionalized-polyethylene grafted on the glass surface. For that purpose, the asymmetric double cantilever beam test was used to determine the fracture energy, Gi, of the interface. On both high-density and low-density polyethylene/glass joints, the fracture energy of the interface,...
