摘要:
Synthetic resins are obtainable by chemically bonding one or more compounds of the general formula I ##STR1## where R.sup.1 is --OH, --NH.sub.2, ##STR2## --NHR.sup.3 or ##STR3## R.sup.2 is --H, --CH.sub.3 or --C.sub.2 H.sub.5, R.sup.3 is --C.sub.m H.sub.2m+1, where m is from 1 to 6, R.sup.4 is --H or --CH.sub.3 and n is from 1 to 12, via the oxygen or nitrogen atom of R.sup.1 to one or more polymers A which consist ofa) 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) andb) 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.
