ABSTRACT:
Macromolecular species such as enzymes, proteins, drugs, and solid supports which contain reactive carbonyl groups or groups which are readily converted to reactive carbonyl groups are modified by reaction with a compound of the formula ##STR1## in which R.sup.1 is H, C.sub.1 -C.sub.20 alkyl, phenyl, (C.sub.1 -C.sub.10 alkyl)-substituted phenyl, or phenyl-substituted C.sub.1 -C.sub.10 alkyl; R.sup.2 is C.sub.2 -C.sub.5 alkylene or (C.sub.1 -C.sub.4 alkoxy)-substituted C.sub.2 -C.sub.5 alkylene; R.sup.3 is ##STR2## R.sup.4 is H or C.sub.1 -C.sub.4 alkyl; n is at least 5; and m is zero or 1.
