摘要
The invention concerns specifically emulsion polymers which are intraparticulately crosslinked via a hetero-Diels-Alder (HDA) mechanism. The crosslinked polymers can then be wholly or partly decrosslinked by thermal processing, for example in the form of a composite matrix, via a retro-Diels-Alder or retro-hetero-Diels-Alder reaction and interparticulately recrosslinked on cooling. This makes it possible to prepare long shelf life prepregs for composites. But it is also possible to thus realize other materials that have thermoset properties at use temperature but thermoplastic processing properties at a higher temperature.
