摘要： A refrigerator interior liner can be made of a composition including a monovinylaromatic polymer matrix having an average molecular weight in weight Mw above 150,000 g/mol; rubber particles; and low- Mw plasticizers. The rubber particles can have an RPS volume of about 8.5 μm, a monomodal distribution, a swell index above 13.8, and an RPVF of at least 39%. The composition can be prepared by forming a polymerizable mixture including a monovinylaromatic monomer, and dissolving a viscous rubber in the polymerizable mixture. A free radical initiator and a chain transfer agent can be contacted with the polymerizable mixture at conditions whereby phase inversion subsequently occurs. The chain transfer agent can produce an increase of the rubber to PS phase viscosity ratio within the inversion reactor.

In another embodiment b1 doesn't comprise the metal alkoxide M(OR9)x and there is no ratio OH/b1.
