DISPERSITY OF THE COPOLYMER OF STYRENE AND 2, 2, 6, 6-TETRAMETHYL-4-PIPERIDINYL-METHACRYLATE (PDS) IN POLYPROPYLENE AND ITS INFLUENCE ON PHOTOSTABILIZING ACTION OF PDS*
摘要:
The morphology of films of PDS/PP blends with various contents of PDS and with PDS of dif-ferent molecular weights was examined by scanning electron microscopy and the photostability of these films was studied by infrared spectrometry. Experimental results show that PDS is dispersedin PP matris as spherical globules being in size of the order of 10-1μm when content of PDS is in therange of 0.1 % to 1%. The phase separation of PDS from PP results in decrease in photostabilizingaction of PDS to some extent.It is found that films of PP blended with PDS of different molecular weights show similar morphology and photostabilizing action if the content of PDS is kept constant.
