| abstract | Process for the manufacture of a graft copolymer B, consisting of: B1: 40 to 85% by weight, based on the content of solid substance of graft copolymer B, of a graft base (B1), which can be obtain through (a) polymerization of: (B11): 0 to 10% by weight, with respect to the graft base B1, of at least one vinyl aromate, in particular styrene, and (B12): 90 to 100 % by weight, with respect to the graft base B1, of at least one diene, in particular butadiene, in which (B11) and (B12) result in 100% by weight; and (b) agglomeration of the graft base B1 obtained through the addition of (C): 0.01 to 5 parts by weight, with respect to 100 parts by weight of the graft base B1, respectively, with respect to content of solid substance, of a copolymer (C) having an agglomerating action of: (C1): 80 to 99.9% by weight of one or more hydrophobic C1-C12 alkyl acrylates or C1-C12 and (C2) alkylmethacrylates : 0.1 to 20% by weight of one or more hydrophilic comonomers, which are selected from the group consisting of acrylamide, methylacrylamide, ethylacrylamide and n-butylacrylamide, in which (C1) and (C2) result in 100% in weigh; and B2: 15 to 60% by weight, with respect to the solid substance content of the graft copolymer B, of a graft sheath that can be obtained through the reaction of the graft base B1 agglomerated with a mixture of: (B21 ) 70 to 90% by weight, based on the graft sheath (B2), of styrene and / or α-methylstyrene, in particular styrene, and (B22) 10 to 30% by weight, relative to the sheath of graft (B2), of acrylonitrile and / or methylmethacrylate, in particular acrylonitrile, in which the total sum of the graft base B1 and the graft cover B2 results in 100% by weight; in which: (i) the binder action copolymer (C) has a polydispersity U of 0.26 to 0.20 and a d50 value of 115 to 140 nm, and (ii) the agglomerated graft base B1 has a bimodal particle size distribution of a fraction x) of non-agglomerated particles with a d50-value in the range of 80 to 120 nm and a fraction y) of agglomerated particles with a d50-value in the range of 350 to 450 nm and a polydispersity U in the range of 0.27 to 0.20, and the process is characterized by: (i) polymerization of monomers B12 and B11 in aqueous emulsion to obtain a graft base B1 in the form of particles, (ii ) agglomeration of the graft base B1 in the form of particles which is present in an emulsion by means of a copolymer (C) with binding action, in which the copolymer (C) has a polydispersity U in the range of 0.25 to 0.20 and a d50 value of 115 to 140 nm, to obtain a graft base B1 in the form of agglomerated particles, and then (iii) polymerization of the monomers B21 and B22 of the graft sheath in aqueous emulsion in the presence of the graft base B1 in the form of agglomerated particles. |
