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.
