Effects of small‐amplitude oscillatory shear on polymeric reaction
Source abstract
Abstract
Abstract The effects of small‐amplitude oscillatory shear on the polymeric reaction between poly(butylene terephthalate) (PBT) and epoxy in melts were studied. Two kinds of samples, sandwich sample and blending sample, were prepared for reaction kinetics by using a new rheological method which correlates the change of the rheological property of reactive system with the conversion of the in situ formed copolymers. The results indicated that the reaction between PBT and epoxy was hardly affected by the small‐amplitude oscillatory shear. The increase of apparent reaction rate in sandwich sample was due to the increase of molecular diffusion by oscillatory shear. POLYM. COMPOS., 29:72–76, 2008. © 2007 Society of Plastics Engineers
