NOVELTY - Composition comprises one or more vinyl ether monomers, which exhibit one or more ethyleneoxy groups and at least one carbocyclic group, and a further component comprising (a) vinylether compounds (I) or (b) a lipophilic, non-polymerizable component comprising a polymeric hydrocarbon having a molecular weight of 1000-10000 and/or a cyclohexylene compound (II), where the total content of vinyl ethers and fluorovinylethers are at least 50 wt.%.    USE - The composition is useful as: adhesive, coating or sealant in optoelectronic devices; and as the polymer orientation in a polymer-stabilized vertical-alignment (PS-VA) display device (all claimed). The composition is useful for sealing, encapsulating, adhering, or coating optoelectronic components, such as organic LEDs, solar cells, optical sensors, and liquid crystal displays, or for orienting liquid crystals.    ADVANTAGE - The composition exhibits good curing and wetting characteristics and good strength. The composition exhibits improved adhesive properties so that can be used in display manufacturing which allows the mass production of short process times and thus leads to significant cost savings and have a high barrier effect against water vapor.    DETAILED DESCRIPTION - Composition comprises one or more vinyl ether monomers, which exhibit one or more ethyleneoxy groups (-O-CH=CH2) and at least one carbocyclic group, and a further component comprising (a) vinylether compounds of formula (I) or (b) a lipophilic, non-polymerizable component comprising a polymeric hydrocarbon having a molecular weight of 1000-10000 and/or a cyclohexylene compound of formula (II), where the total content of vinyl ethers and fluorovinylethers are at least 50 wt.%.    R1-R3 = H, fluorinated or unsubstituted, linear or branched 1-15C-alkyl, where one or more non-adjacent CH2 groups are optionally replaced by -CH=CH-, -(CO)-, F, Cl, -O or -S-, and the O or S atoms are not directly bonded to one another;    p1, p3, n1, n3 = 0-5, where p1+n1 and p3+n3 are 0-5;    p2, n2 = 0-4, where p2+n2 is 0-4 and p1+p2+p3 is greater than or equal to 1;    X = Q-O-CH=CH2, Q-O-CH=CF2 or Q-O-CF=CF2;    Q = single bond, -CH2- or 2-10C-alkylene, in which one or more CH2 groups are optionally replaced by -O- or -S-, and O atoms are not present as adjacent atoms;    A1-A3 = 1,2-, 1,3- or 1,4-cyclohexylene, 1,2-, 1,3- or 1,4-cyclohexenylene, 1,2-, 1,3- or 1,4-phenylene (where CH2 groups are optionally substituted by O, =CH- or =N-), or spiro(3.3)heptan-2,6-diyl;    Z1, Z2 = single bond, -CH2CH2-, 3-6C-alkylene, -CF2CF2-, -CH2O-, -CF2O-, -OCH2-, -OCF2-, -C?=C-;    R4, R5 = 1-10C-alkyl, in which one or more CH2-groups are optionally replaced by CH=CH-, or H by F;    A4, A5 = 1,2-, 1,3- or 1,4-cyclohexylene, 1,2-, 1,3- or 1,4-cyclohexenylene, 1,2-, 1,3- or 1,4-phenylene;    Z4 = single bond, (-CH2-)r, -CH=CH-, -C?=C-, -CF2-CF2- or -CF2O-; m1-m3 = 0-2, where m1+m2+m3 is 2-6; and    r = 1-6.    Where X is -OCH=CH2 and A1-A3 is bonded to a phenyl group, then each A1 in the ortho-position to X is not substituted by H. INDEPENDENT CLAIMS are included for:    (1) an optoelectronic device, where the edge or the entire area of the device is sealed, encapsulated or coated by the composition; and    (2) producing the optoelectronic device consisting of several layers, where these layers comprise a flat substrate and a cover layer, comprising (i) applying the composition to the substrate and/or the cover layer, and optionally a first curing, (ii) bonding the planar substrate and the cover layer, so that the composition comes to rest in between them, and (iii) curing the composition.
