As a class of recyclable thermoset, vitrimers are generally constructed by introducing dynamic chem. into various synthetic or biobased building blocks. Particularly, biobased vitrimers have aroused increasing interest because of the utilization of renewable resources. The wide range of constructing resources and the different mech. properties of the resulting networks highlight the fusion of vitrimers with distinct mech. properties in the recycling process. However, most vitrimers have only been investigated in terms of their own reprocessability, or fusion of identical polymer networks. Herein, we report the concept of melding two biobased vinylogous urethane vitrimers with distinct mech. properties. Two distinct biobased vinylogous urethane vitrimers were prepared by reacting acetoacetate-modified cardanol with two different diamines (MXDA or PACM). It was found that these vitrimers can be successfully fused and that, after three rounds of hot pressing, the mech. and thermal properties of the fused vitrimer are comparable to that of a homogeneous vitrimer prepared using premixed MXDA and PACM diamines, the ratio of which is the same as the two distinct vitrimers. This capability of fusing two distinct vitrimers also features a flexible window for targeting mech. properties, which can be achieved by simply adjusting the ratio of these two vitrimers.
