Problems solved by technology

However, when this transparent thermoplastic resin is applied to the edge of furniture, whitening occurs during processing, cracks are prone to occur, and whitening occurs at low temperatures
Therefore, there are limitations in the application of ABS resin

[0041] 1) the preparation method of grafted resin (A)

[0042] Graft resin (A), for example, by graft copolymerization weight average rubber particle size is to The conjugated diene rubber latex is prepared with alkyl (meth)acrylate compound, aromatic vinyl compound and vinyl cyano compound.

[0043] As a more specific example, based on the sum of 100 parts by weight of the grafted resin (A), the grafted resin (A) can be grafted by copolymerization (a) 40 parts by weight to 65 parts by weight of the weight average rubber particle size is to Conjugated diene rubber latex (based on solids), (b) 22 to 45 parts by weight of an alkyl (meth)acrylate compound, (c) 7 to 18 parts by weight of an aromatic vinyl compound, and (d) 0 to 10 parts by weight of vinyl cyano compounds.

[0044] In the present disclosure, unless otherwise specified, the alkyl (meth)acrylate compound includes an alkyl methacrylate compound and an alkyl acrylate compound.
