    Abstract: Epoxide-amine adducts (I) are claimed, contg. at least 20 wt% aliphatic epoxide and/or amine units with at least one tert. or quat. carbon atom. Also claimed are: (i) binders for coatings, contg. adduct(s) (I); (ii) mixts. of 0.1-99.9 wt% OH gp.-contg. copolymers and 99.9-0.1 wt% (I); (iii) binders for coatings, contg. mixts. (ii); (iv) coating materials contg. these binders, together with hardeners such as amino resins, capped or uncapped polyisocyanates and cpds. with acid and/or anhydride gps.. Pref. (I) are obtd.: (A) by reacting (a) 7-33C (cyclo)aliphatic mono-epoxides (a1), at least 20 wt% of which comprises monoepoxides with a tert. or quat. C atom with (b) 2-30C amines with at least 2 prim. or sec. amino gps. not attached directly to an aromatic ring; or (B) by reacting (a) 8-50C (cyclo)aliphatic diepoxides (a2) with (b) 4-30C prim. or sec. mono-amines with amino gps. not directly attached to aromatic rings, of which at least 20 wt% comprises mono-amines with at least one tert. or quat. C atom; or (C) by reacting (a1) with (b), the corresp. proportions of mono-amine and mono-epoxide with tert. or quat. C atoms being a% and b% respectively, where a + b = 20 and both a and b are greater than zero. The functionality of (I) is reduced by partial or complete reaction of the functional OH and amino gps., pref. by blocking with temporary protecting gps., esp. oxazolidine gps..

    Abstract: A polymer alloy contains at least one cycloolefin polymer and/or at least one polyolefin and a block copolymer as phase promoter, which has different contents of monomers (norbornene derivatives and cycloolefins and/or acyclic olefins) in the individual blocks. To prepare the alloy, the individual polymers are combined and processed at elevated temperature under the action of shear forces.

    Abstract: Prepn. of low mol. wt. functional polymers comprises: (1) preparing a first quantity of a mixt. (M1) from at least one component chosen from olefinic unsatd. monomers (B) and cpds. (A) which do not copolymerise with (B) but can react to form a copolymerisable addn. reaction cpd.; (2) starting polymerisation by the addn. of initiators and opt. regulators; and (3) adding an additional quantity (M2) of the (A)/(B) mixt. during polymerisation, the compsn. of (M2) being the same as or different to (M1), with the provision that an oligomer or polymer (C) is dissolved in at least one of (M1) or (M2), and at least one of (M1) or (M2) contains a component (B). Also claimed are: (i) copolymers prepd. by the process, and (ii) binders for lacquers which contain these copolymers, as well as cross-linking agents chosen from isocyanates, melamine resins or epoxy cpds.
