| Abstract: | In this paper,the effects of structure of polyurethane and the mixture of other materials with polyurethane on the heat-resistance of polyurethane elastomers were reviewed.The introduction of rigid groups,the structure of hard segment and soft segment all can improve the thermal stability of polyurethane.Both the mixture of inorganic materials,organic materials with polyurethane and the interpenetrating polymer networks can reinforce the heat-resistance of polyurethane. |
