Patent ID: 8785545

Claim:
A refrigerator interior liner made of a rubber modified monovinylaromatic polymer composition comprising: a) a monovinylaromatic polymer matrix having an average molecular weight in weight Mw above 150,000 g/mol, b) rubber particles dispersed in the monovinylaromatic polymer matrix, said rubber particles having: a volume median particle size (RPS volume) of about 8.5 μm, a monomodal distribution with essentially no shoulder, a low-to-moderate crosslinking of the rubber expressed as a swell index (SI) above 13.8, a rubber phase volume fraction (RPVF) of at least 39%, c) an amount of low- Mw plasticizer, defined as the weight fraction of solubles in methanol, and such that the weight ratio c/(a+b+c) ranges from 1 to 4.5%.
