SYNTHETIC RESINS

摘要

O.Z. 0050/41632 Synthetic resins are obtainable by chemically bonding one or more compounds of the general formula I (I) where R1 is -OH, -NH2, , -NHR3 or R2 is -H, -CH3 or -C2H5, R3 is -CmH2m+1 where m is from 1 to 6, R4 is -H or CH3 and n is from 1 to 12, via the oxygen or nitrogen atom of R1 to one or more polymers A which consist of a) from 50 to 100% by weight of one or more esters of acrylic or methacrylic acid with monohydric alcohols of 1 to 18 carbon atoms or a mixture of these esters (monomers a) and b) from 0 to 50% by weight of other copolymerizable monomers (monomers b) in polymerized form, in amounts such that the synthetic resin contains from 0.01 to 1 mole of double bonds per kg of polymer A. After exposure to ultraviolet light or to electrons, these synthetic resins are suitable as contact adhesives.
