This comprehensive study paves way to investigate the effects of not only the extent of grafting but also the chain length of the perfluorinated pendant tail presenting in the three different fluoroalkyl acrylate monomers on the significant characteristic properties; namely the thermal behavior, crystal structure quality, mechanical performance and morphological structure of high density polyethylene (HDPE). The individual graft copolymerizations of the monomer onto HDPE were conducted at the content level from 5 % to 30 % via bulk-melt polymerization. The characterizations of copolymers were performed with differential scanning calorimeter (DSC), powder X-ray diffractometer, universal testing machine and scanning electron microscope (SEM) techniques. As for the results deduced from DSC analysis, both the melting temperatures of HDPE and degree of crystallinity were found to increase systematically with the enhancement in the percent grafting level up to 10 % beyond which the parameters were noted to decrease drastically and reach towards globally minimum values. According to the XRD results, as the percentage of grafting enhanced, the remarkable expansions were observed in unit cell parameters of HDPE crystallized in the orthorhombic symmetry. Moreover, the presence of relatively higher amount of -CF₂ groups in the perfluorinated pendant tail caused the formation of three-dimensional lateral repulsions due to its helix structure. Furthermore, there seemed to remarkably improve in the mechanical performance features in case of percent grafting level of 70.6 % where the tensile strength, Modulus and impact strength parameters were measured to be about 42.51 MPa, 539.90 MPa and 41.11 kj/m², respectively. These reinforcements were found to be explained by the improvement in the regulation, orientations, alignments of HDPE chains. Furthermore, the formation of thick, bulky and long-fibrils were observed at high percent grafting.

这项全面的研究不仅研究了接枝程度，而且还研究了三种不同的丙烯酸氟代烷基酯单体中存在的全氟侧链尾部的链长对显着特性的影响。即高密度聚乙烯（HDPE）的热行为，晶体结构质量，机械性能和形态结构。通过本体熔融聚合，单体在HDPE上的接枝共聚反应的含量为5％至30％。用差示扫描量热仪（DSC），粉末X射线衍射仪，通用测试仪和扫描电子显微镜（SEM）技术进行共聚物的表征。至于DSC分析得出的结果，发现HDPE的熔融温度和结晶度都会随着接枝百分率的提高而系统地提高至10％，超过10％则表明该参数急剧降低并达到全局最小值。根据XRD结果，随着接枝百分比的增加，在正交晶系对称的HDPE晶胞参数中观察到显着的扩展。而且，存在相对较高数量的-CF 在正交晶系对称的HDPE晶胞参数中观察到显着的扩展。而且，存在相对较高数量的-CF 在正交晶系对称的HDPE晶胞参数中观察到显着的扩展。而且，存在相对较高数量的-CF全氟悬垂尾部中的₂组由于其螺旋结构而引起三维横向排斥的形成。此外，在接枝百分含量为70.6％的情况下，机械性能特征似乎显着改善，其中测得的抗拉强度，模量和冲击强度参数分别为约42.51MPa，539.90MPa和41.11kj / m ²。发现这些增强可以通过改善HDPE链的调节，取向和排列来解释。此外，在较高的接枝率下观察到了厚，膨大和长纤维的形成。
