Toluhydroquinone and methyl / fX butyUiydroquinone provide improved resin color retention 2,5-di-/-butyIhydroquinone also moderates the cure rate of the resin. Quaternary ammonium compounds, such as benzyl trimethyl ammonium hydroxide, are effective stabilizers in combination with hydroquinones and also produce beneficial improvements in color when promoted with cobalt octoate. Copper naphthenate is an active stabilizer at levels of 10 ppm at higher levels (150 ppm) it infiuences the cure rate. Tertiary butylcatechol (TBC) is a popular stabilizer used by fabricators to adjust room temperature gelation characteristics.

The relationship of protein hydrophobicity to the gelation characteristics of proteins has been reported by a number of workers [57,77,78,79,80], There appears to be an optimal level of hydropho-... 

Other polymer properties that are often measured are whiteness, color, thermal stability, glass transition temperature (wet and dry), melting point (wet and dry), dope viscosity, and gelation characteristics. Techniques used for characterizing acrylic textile polymers are summarized in Table 12.30.
