A substance which represents an intermediate stage in polymerization, and can be usefully manipulated before polymerization is completed.
〔化〕预聚物
the prepolymer forms a polymerized gel when activated
Example sentencesExamples
Artificial clays containing a catalyst can initiate polymerization when the particles are mixed with a prepolymer matrix.
Siloxanes are prepolymers - the result of partial polymerization of silanes - in which the molecules are beginning to link, but only in sets of two or three, not yet in full chains.
‘The ultimate resolution is correlated to the ability of the prepolymer to conform to the surface and the ability of the cross-linked polymer to retain the molded shape,’ Rogers said.
Some researchers believe that prepolymers achieve better results.
