Abstract
4-Vinylbenzaldehyde (3) was complexed with methylated β-cyclodextrin (4) (me-β-CD) yielding the water soluble host-guest complex (5). Radical polymerization was initiated with K 2 S 2 O 8 /Na 2 -S 2 O 5 in water at room temperature and also at 70°C. The polymerization tendency of this complex (5) is lower compared to the styrene/me-β-CD-complex (7). Also copolymerizations of 5 and complexed styrene (6) at these two temperatures were carried out and the results are discussed in respect to the behavior of the homopolymerization. The resulting polymers (8a-k, 9a, 9b) were characterized by SEC-measurements and 1 H NMR spectroscopy. TEM-measurements of the homopolymers 8f and 8k show differences in the particle size depending on the amount of me-β-CD.
