Abstract
Bisphenol A-type cyanate ester (BACE) was modified by carboxyl terminated liquid nitrile rubber (CTBN) exhibiting shape memory properties. Shape memory BACE/CTBN copolymer was a new kind of smart materials, which has huge development potential and promising future. A series of shape memory BACE/CTBN copolymers were prepared by varying mass ratio of BACE and CTBN. The mechanical performance, thermal properties, and shape memory effect of the BACE/CTBN copolymers were systematically investigated. It was found that the BACE/CTBN copolymers have excellent shape-memory behavior, and the glass transition temperature (T g ) of the copolymers can be adjusted with the content of CTBN. The shape recovery speed increases with the increment of the content of CTBN and the shape fixed ratio and shape recovery ratio are almost 100 %.
