Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>The cold crystallization behavior of poly (<sc>L</sc>‐lactide) (PLLA) blend films modified by small amount of acrylic rubber particles (ACR) have been investigated by <italic>in situ</italic> Fourier‐transform infrared (FTIR) spectroscopy. During the isothermal cold crystallization, the crystallization rate of PLLA is greatly improved with addition of only 1 wt % ACR. However, for PLLA with 8 wt % ACR, the crystallization rate is slower than that of neat PLLA. The relative crystallinity of PLLA with the addition of 1–5 wt % ACR is obviously higher than that of the neat PLLA. For the PLLA blend film with 3 % ACR, the relative crystallinity reaches a maximum. It was found that the addition of ACR particles below 5% accelerated the cold crystallization nucleation process and made the cold‐crystallization rate of PLLA/ACR be quicker than that of neat PLLA. © 2012 Wiley Periodicals, Inc.
