中文摘要	two types of macromolecular free radicals similar to ch2conh(c) over dothch(2) similar to (a) and similar to ch2(c) over dot = o (b) trapped in irradiated polyamide-1010 (pa1010) and pa1010 filled with neodymium oxide (nd2o3) were characterized by an esr approach. it is found that (a) is prevailingly trapped in the fold surface of the lamellae and (b) in the amorphous phase. this result suggests that trapped radicals mainly exist in the non-crystalline phases. the effect of the fold surface area of the lamellae on the behavior of the trapped radicals is discussed in this paper. whether for the specimens with similar crystallinities, but different crystallite sizes, or for those with the same concentration of neodymium oxide, but different crystallinities, radical (a) exists dominantly in the specimen with a larger fold surface area of the lamellae. under certain circumstances, radical (a) can transform into radical (b), obviously for a specimen with a larger fold surface area of the lamellae. it means that the fold surface area of the lamellae plays an important role in the transformation of radical (a) to (b).
