Definition of prepolymer in English:

prepolymer

noun priːˈpɒlɪməprēˈpäləmər

Chemistry

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.
