ml of chloroform in 250 ml portions air drying followed by vacuum drying at room temperature yielded 121 1 g of product the infrared spectrum of this material showed strong nh absorption a strong band at 8 1 u03bc and a weaker but broader band at 10 7 u03bc an aqueous solution of the product was weakly alkaline the material was insoluble in chloroform acetone and cold methanol ______________________________________ found______________________________________ h n 37 80 p 24 42 cl 13 73______________________________________ a thermogravimetric analysis revealed that nearly 41 of the material was lost between 25 and 300 u00b0 c but from 300 715 u00b0 c only 3 additional weight loss occurred in helium in air the weight loss was similar but from 650 900 u00b0 c another 14 was lost a solution containing the desired weight percent of the product in sufficient water to just saturate the cloth was poured on a weighed piece of cloth lying flat in a plastic bag the solution was worked over the surface of the cloth until it was uniformly wet after standing for about fifteen minutes the cloth was placed in an oven at the desired temperature and cured after curing and drying the cloth was allowed to equilibrate before being weighed cure was effected at 140 u00b0 c using.
