Water dilutable resins contg. quat. ammonium gps.

摘要

Quat. ammonium gp.-contg., water dilutable synthetic resins contg. at least one basic sec. and/or tert. amino gp. per quat. ammonium gp. are made by reacting (A) a quat. ammonium salt with a mol. wt. of ca. 175-1200 made by neutralisation of (a) an organic cpd. with at least two basic amino gps./mol. of which one is a prim. amino gp. which is protected by previous reaction with a ketone to form the ketimine, and the remaining basic amino gps. are tert., opt. in an inert organic solvent, with (b) 15-100 mol.% w.r.t. the amino gp. in (a) of an (in)organic acid, and subsequently reacting with (c) 15-100 mol.% w.r.t. N atoms in component (a) of at least one monoepoxide cpd. (II) at temps. of 50-100 deg.C, and opt. hydrolytically splitting off the protective gp., with (B) 1-4 equivs. of an epoxide gp.-contg. resin with an ave. mol. wt. Mw of 300-6000 and an ave. of 1.5-3.0 epoxy gps./mol., per protected or deblocked prim. amino gp. in (A), at temps. of 30-130 deg.C until the theoretical drop in epoxide value is achieved, and opt. reacting remaining epoxide gps. with a monofunctional organic cpd. (III) with a functional gp. capable of addn. to an epoxide, with the exception of tert. amines and their salts. - The reaction is continued until practically no epoxide gp. is still detectable. Reaction of the quat. ammonium salt (A) with components (B) and (C) may also be carried out in a single stage.
