The olefin cross metathesis reaction comes down to an apparent interchange of carbon atoms between two double bonds. The metathesis reaction was carried out in dichloromethane using the mixture of frationated polyester containing C=C double bonds in its backbone structure and 1,4-polybutadiene in the presence of Grubbs catalyst. DSC analyses of the polymer obtained in the reaction was carried out. In the case of polyester/polybutadiene blend, melting endothermic peak and glass transition temperatures derived from polyester and polybutadiene were observed. On the other hand, the lowering of melting point was confirmed in hybrid polymer after macromolecular metathesis reaction. This result indicates that the length of the main chain of polyester is shorter than that of original polyester, and the lamellar thickness of the polyester crystal decreased in the hybrid polymer.
