Abstract
- In this study, we used vinyl acetate (VAc), N-hydroxymethyl acrylamide (NMA), and montmorillonite (MMT) to prepare polyvinyl acetate (PVAc), PVAc-NMA, PVAc-MMT, and PVAc-NMA-MMT. Dynamic mechanical and thermogravimetric analysis revealed their glass transition, cold crystallization, and pyrolysis kinetics. PVAc-NMA, PVAc-MMT, and PVAc-NMA-MMT can be applied in harsh or low temperature conditions and surroundings. They are homogeneous amorphous linear polymers and all have cold crystallization phenomena. NMA and MMT did not have any significant effect on pyrolysis temperatures, but delayed the thermal degradation processes. The glass transition, cold crystallization, and pyrolysis kinetics were analyzed using Agrawal integral equation. C � 2013 Wiley Periodicals, Inc.
