Title (EN) ALKYL METHACRYLATE/ALKYL ACRYLATE COPOLYMERS USED AS SIZING FOR REINFORCING FIBER
(FR) COPOLYMÈRES DE MÉTHACRYLATE D'ALKYLE/ACRYLATE D'ALKYLE UTILISÉS EN TANT QU'ENCOLLAGE POUR FIBRE DE RENFORCEMENT
Abstract:
(EN) Reinforcing fiber for use in thermoplastic or thermosetting matrix resin are sized with one or more copolymer composition(s) obtainable by reacting: a) 5-90 pphwm of at least one alkyl methacrylate having a Tg of more than 40°C; and b) 5-50 pphwm of at least one alkyl acrylate having a Tg of less than 0°C; and c) 0.1-20 pphwm of at least one C3-C6 unsaturated carboxylic acid; and d) at least one further comonomer selected from the group comprising: (i) 5-50 pphwm of at least one vinyl ester of neoalkanoic acid, and (ii) 10-60 pphwm of at least one vinyl ester of α-monosubstituted fatty acids, and (iii) 5-50 pphwm of vinyl esters of an aromatic carboxylic acid, and (iv) other comonomers.
(FR) La présente invention concerne des fibres de renforcement destinées à être utilisées dans une résine à matrice thermodurcissable ou thermoplastique qui sont encollées avec une ou plusieurs composition(s) de copolymères pouvant être obtenues en faisant réagir : a) de 5 à 90 pphwm d'au moins un méthacrylate d'alkyle ayant une Tg supérieure à 40°C; et b) de 5 à 50 pphwm d'au moins un acrylate d'alkyle ayant une Tg inférieure à 0°C; et c) de 0,1 à 20 pphwm d'au moins un acide carboxylique insaturé en C3 à C6; et d) au moins un comonomère supplémentaire choisi dans le groupe comprenant : (i) de 5 à 50 pphwm d'au moins un ester vinylique de l'acide néoalcanoïque, et (ii) de 10 à 60 pphwm d'au moins un ester vinylique d'acides gras α-monosubstitués, et (iii) de 5 à 50 pphwm d'ester vinyliques d'un acide carboxylique aromatique, et (iv) d'autres comonomères.
