Destruction of thermoplastics by powerful heat fluxes

It is shown that near the irradiated surface, separation of the microstructures (PMM and PS), leading to the formation of a vapor-droplet zone in front of the specimen, takes place. In the case of PC specimens the vapor-droplet zone is chiefly composed of polymer in the gas phase. The temperature distribution near the specimen has been measured and the relation between the surface temperature and the power of the incident heat flux has been established. The linear rate of destruction is found to oscillate about the mean. A theoretical description of the process is proposed.
