The Food and Drug Administration (2001) has established regulations for the use of<br />

polymers and copolymers of styrene in products in contact with food in the USA. For<br />

styrene and methyl methacrylate copolymers as components of paper and paperboard in<br />

contact with fatty foods, the monomer content in the copolymer is limited to 0.5%. For<br />

styrene–acrylic copolymers, the level of residual styrene monomer in the polymer should<br />

not exceed 0.1% by weight.<br />
