蜡结晶会对原油流动造成严重损害，因为随着粘度的增加，在管线中会有有机物沉积，从而导致原油产量下降。乙烯-乙酸乙烯酯共聚物（伊娃）被用作防止此类问题的替代物。本文研究了伊娃共聚物对石蜡和石油沥青残渣（PAR）混合溶剂合成蜡体系性能的影响。伊娃作为防蜡剂的性能取决于共聚物的分子量和乙酸乙烯酯含量以及沥青部分的存在。© 2002 Wiley Periodicals，Inc.应用聚合物科学杂志85：1337-1348，2002
Wax crystallization can cause serious damage to petroleum flow because as the viscosity increases, there is organic deposition in the pipe lines, which causes oil production reduction. Ethylene–vinyl acetate copolymers (EVA) are used as an alternative to prevent such problems. The influence of EVA copolymers on the properties of wax synthetic systems, composed of a solvent mixture and paraffin and petroleum asphalt residue (PAR), was evaluated in this work. The performance of EVA as a wax inhibitor depends on the molecular weight and vinyl acetate content of the copolymer and on the presence of the asphalt fraction. © 2002 Wiley Periodicals, Inc.
