1. A polyalkylether photoinitiator of the general formula I
R1(A1)r-(R2((—CH2CH2O)tA2)m-O)o—(R3((CH2CH2O)tA3)n-O)p—R4(A4)s Iwherein R2 and R3 are independently at each occurrence identical or different, linear or branched alkylene or cycloalkylene groups; wherein R2 and R3 may be substituted with one or more substituents selected from CN; azides; esters; ethers; amides; halogen atoms; sulfones; sulfonic derivatives; NH2 or Nalk2, where alk is any C1-C8 straight chain alkyl group, C3-C8 branched or cyclic alkyl group;
R1 is a linear or branched alkyl or cycloalkyl group or aryl group or is selected from H, OH, CN, halogens, amines, amides, alcohols, ethers, thioethers, sulfones and derivatives thereof, sulfonic acid and derivatives thereof, sulfoxides and derivatives thereof, carbonates, isocyanates, nitrates, acrylates, polyethylenes, polypropylenes, polyesters, polyamides, polyacrylates and polyurethanes; R4 is a linear or branched alkyl or cycloalkyl group or aryl group or is selected from alcohols, sulfoxides and derivatives thereof, carbonates, isocyanates, nitrates, acrylates, polyethylenes, polypropylenes, polyesters, polyamides, polyacrylates and polyurethanes; and when R1 and R4 are alkyl and aryl groups, each of R1 or R4 may be substituted with one or more substituents selected from CN; OH; azides; esters; amides; halogen atoms; sulfones; sulfonic derivatives; NH2 or Nalk2, where alk is any C1-C8 straight chain alkyl group, C3-C8 branched or cyclic alkyl group; o and p are each a real number from 0-5000 provided that o+p>0; m and n are each a real number from 0-10, provided that m+n>0; r and s are each a real number from 0-5; t is an integer from 1-100; and A1, A2, A3 and A4 are identical or different photoinitiator moieties. |
