Fund Project:

A series of AB crosslinked polymers (ABCPs) based on poly(hexamethylene adipate)-polyurethane(PHAPU) and methyl methacrylate(MMA) with various compositions were pre-pared by means of ultra-violet initiation polymerization. The values of crosslink density were determined by swelling equilibrum approach and rubberlike elasticity. The both results were in good agreement. The width of tangent δ peak at the half height was more than 60℃,and the system was considered to be mechanically compatible.By simply varing the concentration of the constituents, a series of damping materials, With a unique set of properties, could be obtained.
- AB crosslinked polymers,
- polyurethanes,
- dynamic mechanical property,
- swelling equilibrium of polymer
