Title (EN) WHEATHER-RESISTANT POLYACETAL RESIN COMPOSITION
(FR) COMPOSITION A BASE DE RESINE DE POLYACETALS ET RESISTANT AUX INTEMPERIES
Abstract:
(EN) A weather-resistant polyacetal resin composition which comprises: (A) 100 parts by weight of a polyacetal resin, (B) 0.01 to 5 parts by weight of a weather (light) stabilizer, and (C) 0.5 to 60 parts by weight of a graft copolymer comprising an olefin (co)polymer and at least one vinyl (co)polymer chemical combined with each other in a branched or cross-linked structure, and which gives a molding with a surface excellent in weathering resistance and reduced in cracking and discoloration.
(FR) L'invention se rapporte à une composition à base de résine de polyacétals et résistant aux intempéries, qui comprend: (A) 100 parties en poids d'une résine de polyacétals, (B) 0,01 à 5 parties en poids d'un stabilisant (contre l'effet de la lumière) résistant aux intempéries, et (C) 0,5 à 60 parties en poids d'un copolymère greffé comprenant un (co)polymère d'oléfine et au moins un agent chimique à base de (co)polymère de vinyle combinés entre eux dans une structure ramifiée ou réticulée, et qui permet de produire une pièce moulée ayant une surface présentant d'excellentes caractéristiques de résistance aux intempéries et de réduction des phénomènes de fissurage et de ternissement.
