Title:
POLYURETHANE POLYMER, PREPARATION METHOD AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/037369
Kind Code:
A1
Abstract:
The present invention relates to the technical field of high-molecular materials, and particularly relates to a polyurethane polymer, a preparation method and application thereof. Disclosed is application of an aminoimidazoline ketone compound in preparing end capping products of the polyurethane polymer. By means of the application of the aminoimidazoline ketone compound, the polyurethane polymer capable of repeated self-heal for multiple times can be prepared without adding any self-healing agent and any external stimulation. Moreover, the present invention further provides a polyurethane polymer and the preparation method therefor. The polyurethane polymer in the present invention can realize repeated self-heal for multiple times without any external stimulation, and the maximum compression strength thereof can be restored to 96% of the strength before compression.
