Title
(EN) TRANSPARENT IMPACT-RESISTANT THERMOPLASTIC RESIN COMPOSITION
(FR) COMPOSITION DE RESINE THERMOPLASTIQUE TRANSPARENTE ET RESISTANT AUX CHOCS
Abstract
(EN) An aromatic vinyl resin composition comprising: (A) 5 to 40 wt.% graft copolymer which is obtained by polymerizing (a4) 60 to 15 parts by weight of a vinyl monomer in the presence of 40 to 85 parts by weight of rubber particles (the sum of the monomer and the rubber is 100 parts by weight) having a particle diameter of 3,500 to 20,000 Å obtained by adding a copolymer having acid groups to a latex of a rubber formed from (a1) 50 to 100 wt.% diene monomer, (a2) 50 to 0 wt.% vinyl monomer, and (a3) 0 to 3 wt.% crosslinking monomer to coagulate and enlarge the rubber particles, the amount of the acid group-containing copolymer being 0.1 to 15 parts by weight per 100 parts by weight of the rubber; and (B) 95 to 60 wt.% aromatic vinyl resin obtained from (b1) 40 to 100 wt.% aromatic vinyl compound, (b2) 60 to 0 wt.% methacrylate, and (b3) 0 to 20 wt.% other vinyl monomer. The composition gives a molding with improved impact resistance while having intact properties of the aromatic vinyl resin, such as heat resistance and transparency.
(FR) Composition de résine vinylaromatique qui contient (A) 5 à 40 % en poids d'un copolymère greffé qui est obtenu par polymérisation (a4) de 60 à 15 parties en poids d'un monomère de vinyle en présence de 40 à 85 parties en poids de particules de caoutchouc (la somme du monomère et du caoutchouc étant égale à 100 parties en poids) ayant un diamètre des particules de 3.500 à 20.000 Å et obtenu par ajout d'un copolymère possédant des groupes acides à un latex de caoutchouc formé à partir (a1) de 50 à 100 % en poids d'un monomère diène, (a2) de 50 à 0 % en poids d'un monomère de vinyle et (a3) de 0 à 3 % en poids d'un monomère de réticulation pour coaguler et agrandir les particules de caoutchouc, la quantité de copolymère contenant les groupes acides étant de 0,1 à 15 parties en poids pour 100 parties en poids du caoutchouc et (B) 95 à 60 % en poids d'une résine vinylaromatique obtenue à partir (b1) de 40 à 100 % en poids d'un composé vinylaromatique, (b2) de 60 à 0 % en poids de méthacrylate et (b3) de 0 à 20 % en poids d'un autre monomère de vinyle. Ladite composition permet d'obtenir une pièce moulée possédant une résistance améliorée aux chocs, tout en conservant intactes les propriétés de la résine vinylaromatique, telles que la résistance à la chaleur et la transparence.
