Abstract
New phosphonated crossβlinked polymers were synthesized from telomers obtained by reaction between 10βundecenol and dialkyl hydrogenphosphonates. Telomers were studied using MALDIβTOF MS. It was proven that side products were produced, corresponding to crossβesterification reactions of dialkyl hydrogenphosphonate on telomers and to radical additions of telomer on 10βundecenol. The same behavior was also observed with allyl alcohol. Telomers were then converted to resins by methacrylation reactions. Finally, photopolymerization of the different resins synthesized was achieved and influence of the nature of the phosphonate group (diester, monoacid and diacid) was also evaluated.

## Abstract Three dihydrobenzoxazines are synthesized from bisphenol A (BPA), 4,4β²βbiphenol (BIP), and dicyclopentadiene phenol adduct (DCPD). Polydihydrobenzoxazine containing 4,4β²βbiphenol (BIPDB) had the most rigid structure of the three and was found to possess the best mechanical and thermal p
Fifteen novel 4-substituted alkylaminobenzophenones have been synthesized and characterized using NMR, mass spectrometry and microanalysis. Their spectroscopic properties have been determined using u.v. absorption and phosphorescence analysis and the data related to their behaviour on photocuring us
In continuation of our endeavor to develop synthetic resins of improved properties and performance, we report here the synthesis of mixed copolymer resins by the condensation of resorcinol, aniline, and formaldehyde with ortho-, meta-, and para-phenylenediamine separately. The resins were characteri
