    摘要: SOLUBLE ORGANOPHOSPHORUS DERIVATIVES OF CELLULOSE NITRATE PREPARED BY REACTION OF CELLULOSE NITRATE CONTAINING FREE HYDROXYL GROUPS WITH A MONO-FUNCTIONAL ORGANOPHOSPHORYL OR PHOSPHINYL CHLORIDE. THE MODIFIED POLYMERS HAVE MARKEDLY IMPROVED FIRE RESISTANCE, RETAIN SUBSTANTIALLY THE ORIGINAL NITROGEN CONTENT, ARE SOLUBLE IN MOST LACQUER SOLVENTS AND ARE CAPABLE OF FORMING DURABLE FILM AS DECORATIVE AND FUNCTIONAL COATINGS.

    摘要: THIS INVENTION RELATES TO A METHOD FOR PREPARING CARBOHYDRATE-BORON ALKOXIDE COMPOUNDS. UNDER ANHYDROUS CONDITIONS, STABLE COMPOUNDS OF METHYL CELLULOSE AND BORON ALKOXIDES, SUCH AS BORON ETHOXIDE, BORON PROPOXIDE, AND BORON ISOPROPOXIDE, WERE PREPARED IN NEAT BORON ALKOXIDE, THE PARENT ALCOHOL, BENZENE, PYRIDINE, AND/OR ETHYLENEDIAMINE. THE METHOD OF THIX INVENTION HAS AS ITS OBJECTIVE INCREASING THE REACTIVITY OF METHYL CELLULOSE WITH BORON ALKOXIDES BY TREATMENT IN SOLUTIONS OF STRONG BASES, SUCH AS PYRIDINE AND ETHYLENEDIAMINE. FORMATION OF METHYL CELLULOSE-BORON ALKOXIDE COMPOUNDS MODIFIES THE RATE OF OXIDATION OF METHYL CELLULOSE AND IS RELATED TO PREPARING FLAME-RESISTANT PRODUCTS.
