But the photocrossfinking method was not used in industry for a long period because the penetration of the light is limited. The recent work done by Rnby et al. is outstanding in the improvement on this method, and it is competitive to the high-energy irradiation method and the thermalchemistry method. Therefore, the photocrosslinking has a promising prospect in application now. This note is a brief introduction to the results about the theoretical analysis and展开更多
