改性超支化聚酯可作为性能优异的防老剂 经过酚类防老剂改性的超支化聚酯防老剂,在液态化合物异三十烷中的防老性能很大程度上高于常用商业防老剂。此类改性防老剂不适用于固态体系中,但非常适用于液态体系的抗老化稳定剂,如油类、润滑剂等。 威海晨源公司整理自《Synthesis and evaluation of hyperbranched phenolic antioxidants of three different generations》Helena Bergenudd, Petter Eriksson, Chris DeArmittb Bengt Stenberg,Eva Malmstro mJonsson Department of Polymer Technology, Royal Institute of Technology, S-10044 Stockholm, SwedenElectrolux Core Technology and Innovation, Stockholm, Sweden Polymer Degradation and Stability , 2002(76): 503–509
