Abstract
Described herein are polymer compositions comprising a polymer and a molecular sieve having a framework type of AEL, AFO, EUO, FER, HEU, MEL, MTW, MTT, MFI, OFF, or TON. The present polymer composition comprises a toluene content of less than 1.0 mg/m3 and a C6-C16 volatile organic compounds content of less than 3.0 mg/m3. Described herein also are a method of reducing the toluene content contained in polymers.
Claims25
A composition comprising:
- a polymer;
- and
- a molecular sieve having a framework type of AEL, MFI, MFS, MEL, MTW, EUO, MTT, HEU, FER, OFF, or TON,
- wherein the composition comprises a toluene content of less than 1.0 mg/m3, and
- wherein the polymer composition comprises a C6-C16 volatile organic compounds content of less than 3.0 mg/m3, and
- wherein each of the toluene content and the C6-C16 volatile organic compound content is measured by thermodesorption gas chromatography with mass spectrometric detection method.
3 more elements
A method of reducing toluene content contained in a composition comprising a polymer, comprising:
- blending the composition with a molecular sieve having a framework type of AEL, MFI, MFS, MEL, MTW, EUO, MTT, HEU, FER, OFF, or TON to form a blended composition, wherein the toluene content of the blended composition is at least 50% less than a reference toluene content of the composition, wherein the composition is the same as the blended composition but substantially free of molecular sleeve, wherein the toluene content and the reference toluene content are determined by thermodesorption gas chromatography with mass spectrometric detection method.
