Abstract[English]
A desirable balance of heat resistance and flame retardancy is exhibited by a composition that includes specific amounts of a poly(phenylene ether), a poly(phenylene ether)-polysiloxane block copolymer reaction product, a hydrogenated block copolymer of an alkenyl aromatic compound and a conjugated diene, and an organophosphate flame retardant. The composition minimizes or excludes reinforcing fillers, certain adhesion promoters, and addition polymers that include repeat units derived from a glycidyl ester of an,-ethylenically unsaturated acid.[French]
Composition comprenant des quantités spécifiques d'un poly(éther de phénylène), d'un produit de réaction de copolymère séquencé poly(éther de phénylène)-polysiloxane, d'un copolymère séquencé hydrogéné d'un composé alcényl aromatique et d'un diène conjugué, et d'un retardateur de flamme organophosphoré, et présentant un équilibre souhaitable de résistance à la chaleur et de retardement de flamme. La composition minimise ou exclut les charges de renforcement, certains promoteurs d'adhérence et les polymères d'ajout comprenant des unités de répétition dérivées d'un ester glycidylique d'un acide à insaturation éthylénique.
