Reactive Polymers Containing Heterocyclic Groups

Epoxide groups can be easily incorporated into polymers by copolymerization with functional monomers such as GMA. In the last few years, there has been a rapid increase in the munber of literature reports concerning the copolymerization of GMA with other monomers as shown in Table 2.8. GMA copolymerized PS [171, 198, 199, 239-241, 249, 250, 257, 258, 324], PE [233-237, 243, 245], SAN [108, 251, 339], AC [183, 184, 230, 252], and core-shell polymers [262] have been used in blend compatibilization. The terminal epoxide groups inherent in Epoxy resins have been utilized in their reactive

Azo dyes are characterized by the presence of at least one azo group (-N=N-) as the chromophore. Azo dyes may be derived from aminoazobenzene or from a variety of heterocyclic structures. They may be nonionic with no solubilizing constituents, therefore belonging to the disperse application class they may be sulfonated, therefore belonging to the acid application class or they may contain constituents that covalently bond with fiber polymers, therefore belonging to the reactive application class. 

The chemistry involved in curable poly(ester imide) formulations is well established, and it is still based on trimellitic anhydride, methylene dianiline, and low molecular weight polyesters of aromatic dicarboxylic acids and glycols, along with a classical heterocyclic triol, 2,4,6-trishydroxyethyl isocyanurate (THEIC), as it is shown in Scheme (29). The composition is formulated in a way that the final polymers, although linear, contain free —OH groups, both as chain ends and as side reactive groups. At the moment of...
