ABSTRACT
The effects of components on properties of polyurethane high resilience foams synthesized by starch grafting polyether dispersing liquid were investigated. It is shown that this dispersing liquid has improved greatly load-bearing capacity of polyurethane flexible foams. The optimum formulation was given. The major properties of the polyurethane high resilience foams reached the level of ASTM criteria for polyurethane high resilience flexible foams.
