Se describen mejoras en la estabilidad térmica de las composiciones de poliacetal que contienen celulosa microcristalina o celulosa fibrosa como estabilizadores en el proceso de fusión y se obtienen mediante la inclusión de un co-estabilizador a base de poliamida o un polímero que contiene hidroxi fundible o un co-estabilizador oligomérico tal como poli(alcohol etilenvinílico).Improvements in the thermal stability of polyacetal compositions containing microcrystalline cellulose or fibrous cellulose are described as stabilizers in the melting process and are obtained by including a co-stabilizer based on polyamide or a meltable hydroxy-containing polymer or a Oligomeric co-stabilizer such as poly (ethylene vinyl alcohol).
