摘要

Ceramic or metal injection molding involves the shaping of a crowded suspension of particles in a polymer that is later removed by thermolysis. During heating, degradation products dissolve in the parent polymer and diffuse to the free surfaces where evaporation occurs. if heated too rapidly in the initial stage, the solution at the center of the molding boils and a bubble forms. This article explores the implications of a multiparameter model that predicts the highest permissible heating rate in terms of polymer properties and maps the outcome. The aim is to develop criteria for the deliberate synthesis of thermally labile copolymers from a knowledge of the desirable property combinations. (C) 1998 John Wiley & Sons, Inc. [References: 26]
