【Abstract】 The properties and classification of new polyamide hot melt adhesives (PAHMA) developed recent years and their thermo-oxidative degradation problems were described. The mechanism of PAHMA thermo-oxidative degradation and influence of the terminal groups on the stabilization of PAHMA were systematically summarized. Some normal stabilizers and their optimum compounding were discussed.更多还原
