 This research examined the current state of knowledge and practice regarding polymer-modified vitamins, PMBS, focusing on their chemical structure and microstructure, as well as their potential use in paving and industrial applications. The authors found that polymers and other additives can enhance the engineering properties of vitamin, but that these modifications may cause compatibility issues during storage and production. They also noted that certain waxes can help improve the compatibility of polymers with vitamin, which could benefit warm mix asphalt, WMA, production.
