摘要

AbstractPolyesters were obtained from castor oil and dibasic acids for example, malonic, succinic, glutaric, adipic, suberic, and sebacic acids. These prepolyesters were characterized by infrared spectrometry, viscosimetric measurements, and molecular weight determinations (GPC). These prepolyesters were mixed with methyl methacrylate and were subsequently polymerized by free radical polymerization by benzoyl peroxide in the presence of the crosslinker ethylene glycol dimethacrylate. Polyester/poly(methyl methacrylate)‐interpenetrating polymer networks, PPE/PMMA IPNs, were obtained as soft and opaque elastomers by the transfer molding technique. These IPNs were characterized by static mechanical properties, differential scanning calorimetry (DSC), and thermogravimetry. © 1993 John Wiley&Sons, I
