Abstract (en)
[origin: EP1935914A1] New epoxy-terminated polymers (I), carboxy-terminated polymers (II), amino-terminated polymers (XI) and (meth)acrylate-terminated polymers (XII) are based on carboxy-terminated butadiene-acrylonitrile copolymers (CTBN) and polyepoxides (PEP). Epoxy-terminated polymers of formula (I), carboxy-terminated polymers of formula R 2>-(C(OH)(Y 2>)-CH(R 2>')-O-CO-R 1>-COOH) n (II), amino-terminated polymers of formula R 2>-(C(OH)(Y 2>)-CH(R 2>')-O-CO-R 1>-CO-NH-L) n (XI) and (meth)acrylate-terminated polymers of formula R 2>-(C(OH)(Y 2>)-CH(R 2>')-O-CO-R 1>-CO-O-M) n (XII) are new. R 1>divalent residue of a carboxy-terminated butadiene-acrylonitrile copolymer (CTBN), minus the terminal carboxy groups; R 2>residue of a polyepoxide (PEP), minus n epoxy groups; R 2>~ : H or group bonded to R 2>; R 3>residue of a diglycidyl ether (DGE), minus two glycidyl ether groups; Y 1>, Y 2>H or Me; n : 2-4 (especially 2); L : 3-(piperazino)-propyl, 5-amino-4-methylbutyl or 2-aminocyclohexyl; M : -CH 2CH(OH)CH 2-O-CO-C(R 7>)=CH 2 or -R 8>-O-CO-C(R 7>)=CH 2; R 7>H or Me; R 8>divalent residue, preferably alkylene, cycloalkylene or (poly)oxyalkylene. Independent claims are included for: (1) the preparation of (I) and (II); (2) the preparation of functionally terminated polymers of formula R 2>-(C(OH)(Y 2>)-CH(R 2>')-O-CO-R 1>-Q-R 10>-Q 1>) n (XVI), by: (a) preextending a polyepoxide component (PEP) by reaction with an excess of a carboxy-terminated butadiene-acrylonitrile copolymer component (CTBN) of formula R 1>(COOH) 2, at a stoichiometric ratio of carboxy groups to epoxy groups of 2 or more, to give (II); and (b) terminating (II) by reacting with a diglycidyl ether, diamine, (meth)acrylate-functional alcohol or glycidyl ether-functional (meth)acrylate, in a stoichometric ratio of one functional terminal group of the other reactant per COOH group of (II); (3) compositions containing (I) or (II), preferably together with epoxy resin(s) and optionally also high temperature-activated hardener(s) for the resins; and (4) the (I)- or (II)-containing compositions in hardened form. R 10>divalent group; Q : NH; and Q 1>NH 2 or piperazino; Q : O or -OCH 2C(OH)(Y 1>)CH 2O-; and Q 1>-O-CO-C(R 7>)=CH 2; or Q : -OCH 2C(OH)(Y 1>)CH 2O-; and Q 1>2-(Y 1>)-oxiran-2-ylmethoxy. [Image].
