SYNTHESIS AND INVESTIGATION OF ALPHA,OMEGA-METHACRYLOYL POLY (EPOXIDE-CARBOXYLIC ACID) AND ALPHA,OMEGA-METHACRYLOYL POLY (EPOXIDE-PHENOL) MACROMONOMERS

Alpha,omega-methacryloyl terminated macromonomers containing epoxide-carboxylic acid and epoxide-phenolic repetitive units were synthesised. They were prepared in the molecular range from 600 to 2000 g/mol by a two-step reaction. At first prepolymers were formed from bisphenol-A diglycidyl ether and carboxylic acids or phenols and then reacted in a second step with methacrylic acid to the macromonomers. Their structure is proved by elemental analysis, M(n) (vpo)values, IR and NMR spectroscopy. By using HPLC and GPC analysis it was shown that the macromonomers consist of oligomer homologous series. The distribution of the oligomers agrees with the calculated ones. Furthermore HPLC analysis and NMR spectra show that the epoxide rings were opened by S(N1)- and S(N2)-type reactions.
