Random copolymerization of cyclopentadiene (CPD) and styrene initiated by methylaluminoxane was investigated. The copolymer was analyzed using FT‐IR, 1 H‐NMR and differential scanning calorimetry (DSC). The reactivity ratios of the monomers were r CPD = 19.53, r styrene = 0.60. A single glass transition temperature is observed for each copolymer, which is in agreement with a random type copolymer structure. And a cationic initiation mechanism was speculated based on the polymerization results. Copyright © 2006 John Wiley & Sons, Ltd.
