<p>A polymer article having structure (I), where P comprises the basic polymer and groups -L-CH(-X(R1)p)-CH2(-Y(R2)p); L is a part of a pending group utilized for introducing -X(R1)p and -Y(R2)p; X and Y are halogen, N, S and O; R1 is hydrogen, alkyl, acyl or R2 when X is N, O or S; R2 is hydrogen, alkyl, alkylaryl or arylalkyl in which the alkyl part may contain 1-18 carbons, or -R3(-NH-CR4=O)q or -R3(-NH2)q, -CR4=O or poly alkyloxy that may have been terminally acylated or alkylated; p is an integer 0-3, with the provisos a) p depends on X being halogen, O, S or N, and b) that if several groups R2 are present they may be identical or different; R3 is alkyl, -O-alkyl, hydroxyalkyl, phenylalkyl, with up to 18 carbon atoms in the alkyl part, and R4 is C1-18 alkyl. q is an integer>O representing that one or more hydrogens in R3 may have been replaced with -NH2 or -NH-CR4=O. The polymer article may be used as a chromatography separation medium or in solide phase oligonucleotide synthesis.</p> |
