| abstract | The epoxy cpds., which are of gen. formula : R1- NHCOO-R2-)OOC-R3-(COO-CH2-CH-CH2)z)m n (where R1 may be a 4-10C aliphatic gp. or a cycloaliph., arom., araliph, alkylarom. or heterocyclic gp. contg. is not >4 rings which may be substd. by 1-15C alkyl/alkoxy gps., urethane gps., carbamide gps. or halogen atoms, the rings belonging to condensed or non-condensed systems, R2 may be a 2-19C (un)satd. aliph. gp., a gp. derived from polyalkylene glycols or arom., cycloaliph. or heterocyclic gps. of is not >4 rings which may be substd. by 2-10C alkyl gps., R3 may be (un)satd. 2-10C aliph. gps. arom. cycloaliph. or heterocyclic gps. with is not >4 rings which may be substd. by 2-10C alkyl gps., n is 2-4, m is 1-5 and z is 1-5) are made by (a) esterifying polyurethanes contng. >=1 OH gp/molecule with di/polycarboxylic anhyds. and reacting the resulting acids (or their alkali salts) with epoxy cpds. contng. labile halogen at raised temps. or (b) reacting addn. prods. of polyols and di/polycarboxylic anhyds. contng. is not 1 OH and carboxyl gp/molecule (or their alkali salts) with epoxy cpds. contng. labile halogen to form glycidyl esters and then reacting with polyisocyanates, or (c) reacting alkali salts of addn. prods. of polyols and di/polycarboxylic anhyds. contng. is not 1 OH and carboxyl gp/molecule with polyisocyanates to form the corr. alkali salt of carboxylic acid which has no free OH gps. or isocyanate gps. and reacting these with epoxy cpds. contng. labile halogen at raised temps. |
