Patent ID: 11390736

Abstract:
ABS molding composition comprising: (a) 50 to 80 wt.-% SAN copolymer (a) (S/AN ratio 78:22 to 65:35, Mw 80,000 to 250,000); (b) 8 to 25 wt.-% graft copolymer (b) consisting of 15 to 60 wt.-% graft sheath (b2) and 40 to 85 wt.-% graft substrate—an agglomerated butadiene rubber latex—(b1), obtained by emulsion polymerization of SAN in presence of agglomerated butadiene rubber latex (b1) (D50 150 to 800 nm); and (c) 8 to 30 wt.-% SBC block copolymer (vinylarene 58 to 68 wt.-%) comprising diene/vinylarene tapered polymer blocks; exhibiting ultra-high flow melt with good mechanical properties, a process for their preparation and their use for the production of bulky and/or thin walled articles.
