Tuning the dynamic fragility of acrylic polymers by small molecules: the interplay of molecular structures
Yuanbiao Liu, Gaopeng Shi, Guozhang Wu
Abstract
value of mixtures depends on a combined effect of additive bulkiness and HB interaction. The anomalous dynamics was further rationalized not only by the HB-induced flexibility balance between side groups and backbone, but also by the reduction of cooperative rearranging sizes and alleviation of long-chain connectivity in such HB-driven hybrids.
