Correction terms entering NVKH which have not been encountered earlier will now be discussed. In Equation 5.15, NHB is the total number of alcohol-type or phenol-type hydroxyl (i.e., -OH units in carboxylic and sulfonic acid groups are not counted) and amide groups. Urea and urethane groups are not counted in NHB, but instead in N[non amidc. (C=0)- next to nitrogen], and thus contribute only 16 instead of 33 to Ny n-... 

In addition, carboxylic esters, ethers, amides, urethanes, and sulfones are implicitly permitted because polyesters, polyethers, polyamides, polyurethanes, and polysulfones are among the types of polymers allowed under the exemption, as long as these functional groups have not been modified to enhance their reactivity. One such group that would not be allowed is the dinitrophenyl ester of a carboxyhc acid, which is far more reactive due to the activating functionality ... 

The siloxane sequences containing these ends have been joined to other polymeric sequences such as carbonates, ureas, urethanes, amides, and imides. Other functional groups include amines and sulfonic acids, ° ° ammonium groups, epoxides, and chloroalkyl groups. ...
