WebbPolymer Crystals (cont.) Polymers rarely 100% crystalline • Difficult for all regions of all chains to become aligned • Degree of crystallinity expressed as % crystallinity.--Some physical properties depend on % crystallinity.--Heat treating causes crystalline regions to grow and % crystallinity to increase. Fig. 14.11, Callister 6e. Webb5 apr. 2024 · This research investigated the effect of ultraviolet absorber (UV-531) on the properties of epoxy asphalt (EA) binders. EA binders were modified by adding UV-531 absorber at contents of 0, 0.3, 0.6, 0.9, and 1.2 wt%, and composites were then subjected to ultraviolet (UV)-based aging, including UV, oxygen, and heat treatment.
