ABSTRACT:
2,4-Diamino-6(3,3,3-tribromo-1-propyl)-1,3,5-triazine and 2,4-diamino-6(3,3,3-trichloro-1-propyl)-1,3,5-triazine were prepared by the reaction of the corresponding methyl or ethyl .gamma.-tribromo-butyrate or methyl or ethyl .gamma.-trichlorobutyrate with biguanide. The N-methylol derivatives of the diaminotrihalopropyl triazines were prepared by the reaction of the triazines with aqueous formaldehyde. Two pure tetramethylol derivatives were prepared, namely: 2,4-bis[bis(hydroxymethyl)amino]-6-(3,3,3-tribromo-1-propyl)-1,3,5-triazin e and 2,4-bis[bis(hydroxymethyl)amino]-6-(3,3,3-trichloro-1-propyl)-1,3,5-triazi ne. The tetramethylol derivatives were used to impart durable flame retardancy and wrinkle recovery to cellulosic textiles, particularly to cotton. Flame-retardancy was also imparted to wool and to blends of cotton and polyester.
