Notes:
1)relative viscosity is a calculated value of the ratio of absolute solution viscosity to the absolute viscosity of the solvent.it is measured for an 8.4 wt% solution of Elvamide resin in 90% formic acid solvent (0.11 g resin/ml formic acid).the absolute viscisoty of formic acid is determined using a Cannon-Fensker size 75 viscometer.A Brrokfied viscometer is used to vdetermine the absolute viscosity of the elvamide formic acid solution.the spindle and speed should be selected to give a viscosity highest on the 100 scale.viscosities should be determined at 25 ℃.
2)Alcoholic solutions of Elvamide are generally prepared hot with reflux of the solvent mixture. Preferred solvent mixtures are ethanol /water and n-propanol / water – in each case in a ratio of 8 : 2– or the pure alcohols. A good method involves adding Elavmide in portions to the solvent mixture, with stirring. The mixture is then heated to 80 °C and is stirred until the solution becomes clear. This usually takes one to two hours. Stirring should be controlled so that the pellets do not agglomerate.
3)Elvamide are attacked and dissolved by alcohols, methylene chloride, concentrated mineral acids, and formic acid.
