Molded ceramics with simple poly(ethylene-ethylacryate) thermoplastic binders suffer severe distortion during heating associated with relaxation of polymer conformations, but blends of poly(ethylene-ethylacrylate) containing poly(isobutyl methacrylate) resins and polyethylene glycol and mineral additives do not suffer distortions. The polymer blends are characterized using polarized light microscopy and thermal analysis. Crystallinity and spherulite size of the binder are reduced by blending and by the addition of ceramic powder. Plasticizer additives polyethylene glycol and mineral oil phase separate in poly(ethylene-ethyacrylate), but are compatablized by additions of poly(isobutyl methacrylate). The compatibalized plasticizers are able to relax the polymer conformations after molding, avoiding distortion on subsequent heating.
