    Abstract: Compositions which can be crosslinked under an atmospheric oxygen atmosphere by means of ultraviolet irradiation and are based on (meth)acrylate copolymers having a K value of from 10 to 100, obtained by free-radical polymerisation in solid phase or solution of a) 5 to 97.4% by weight of i-amyl acrylate and/or i-amyl methacrylate and b) 0 to 89.9% by weight of (meth)acrylates whose hompolymers have a glass transition temperature of below -30 DEG C, c) 2.5 to 30% by weight of alpha , beta -monoolefinically unsaturated compounds whose homopolymers have a glass transition temperature of above - 30 DEG C, d) 0 to 10% by weight of monoolefinically unsaturated acids and/or anhydrides thereof, e) 0 to 20% by weight of further olefinically unsaturated monomers containing at least one of the following functional groups: hydroxyl, amide, epoxide, ether, ester, urethane, urea, primary, secondary or tertiary amine and ether, and f) 0.1 to 5% by weight of a copolymerisable benzophenone or acetophenone derivative, the sum of the percentages by weight x = a + b + c + d + f in each case being 100.

    Abstract: Method for the production of monoethylenically unsaturated carboxylic esters, in which, after the esterification is complete, a) the product mixture is extracted in a first extraction stage at a temperature of 10 to 40 DEG C with 5 to 30% by volume, based on the product mixture, of water and b) in a second extraction stage at a temperature of 10 to 30 DEG C the aqueous phase from the first extraction stage is extracted with one to four times the amount by weight of alkanol to be esterified.

Phosphorus-free inhibitor compositions (I) containing (a) N-oxyl radical(s) and (b) a compound of formula (X). n = 0-3; R = 1-4C alkyl, 2-4C alkenyl or 7-10C aralkyl. Independent claims are also included for: (i) a method for stabilizing materials containing ethylenic double bond(s) against unwanted polymerisation by adding (I) to the material; (ii) a mixture containing an ethylenically unsaturated compound and an effective amount of (I) as polymerisation inhibitor.
