摘要
Abstract
In order to improve the emulsifying property of low density polyethylene wax,we prepared modified polyethylene wax micro-emulsion with high stability viachemical grafting modification. First, chemical grafting of low density polyethylene was successfully realized by the suspension-swelling graft method using acrylic acid as grafting monomer. Then,with selected reconstituted anionic and non-ionic emulsifier,and under the conditions of emulsion temperature between 90~95℃,emulsifier dosage of 10% polyethylene wax and emulsification for 30min,micro-emulsion of polyethylene wax with high stability was prepared by a phase change emulsion method. Structure of the modified polyethylene wax was characterized by FTIR,which identified that acrylic acid was successfully grafted to the polyethylene wax molecules. Its melting point and crystallization behaviors were also studiedviaDSC technology. The melting points of the modified polyethylene wax and the original polyethylene wax are 102.85℃ and 102.41℃,respectively,and their crystallinity ratio was 77.7%.关键词
