Abstract
The present invention relates to the technical field of polymer materials, and in particular, relates to a polyurethane polymer and a method for preparing the same and use thereof. The present invention discloses use of aminoimidazolinone-based compound in preparing an end-capped polyurethane polymer product, by which the polyurethane polymer capable of achieving repeated self-healing for multiple times without adding any self-healing agent and any external stimulation can be prepared. The present invention further provides a polyurethane polymer capable of achieving repeated self-healing for multiple times without any external stimulation and having a compressive strength restored to at most 96% of the one before compression, and a method for preparing the same.
