Abstract
A rubber modified monovinylaromatic polymer composition may include a monovinylaromatic polymer matrix. The monovinylaromatic polymer matrix may have an average molecular weight in weight Mw above 150,000 g/mol. Rubber particles may be dispersed in the monovinylaromatic polymer matrix. The rubber particles may have a volume median particle size (RPS volume) ranging from 7 μm to 10 μm, a monomodal distribution, a ratio of RPS volume to surface median particle size (RPS surface) that is below 2, a crosslinking of the rubber expressed as a swell index (SI) above 13.8, and a rubber phase volume fraction (RPVF) of at least 39%. A refrigerator interior liner may be made of the rubber modified monovinylaromatic polymer composition.
