Abstract:
A method comprising contacting a first styrenic polymer composition comprising residual styrene monomer with a molecular sieve, and recovering a second styrenic polymer composition comprising a reduced amount of residual styrene monomer. A composition comprising a styrenic polymer having a residual styrene monomer amount of less than 100 ppm produced by contacting a styrenic polymer composition having a residual styrene monomer amount of equal to or greater than 100 ppm with a molecular sieve, and recovering the styrenic polymer having a residual styrene monomer amount of less than 100 ppm. A method comprising providing a styrenic polymer composition having a residual styrene monomer amount of equal to or greater than 100 ppm, contacting the styrenic polymer composition with a molecular sieve, adding a nucleating agent, a foaming agent, and a coloring agent to the styrenic polymer composition, and forming an expanded styrenic polymer composition having a residual styrene monomer amount of less than 100 ppm.
