<p>Novel block copolymers are described, together with the production therefrom of physiologically soluble polymer therapeutics. The block copolymers have the general formula (1) wherein R is selected from the group consisting of hydrogen, C1-C18 alkyl, C2-C18 akenyl, C7-C18 aralkyl, C7-C18 alkaryl, C6-C18 aryl, carboxylic acid, C2-C18 alkoxycarbonyl, C2-C18 alkaminocarbonyl, or any one of C1-C18 alkyl, C2-C18 alkenyl, C7-C18 aralkyl, C7-C18 alkaryl, C6-C18 aryl, C2-C18 alkoxycarbonyl and C2-C18 alkaminocarbonyl substituted with a heteroatom within, or attached to, the carbon backbone; R1 is selected from the group consisting of hydrogen and C1-C6 alkyl groups; R2 is a linking group; X is an electron withdrawing group; R3 is selected from the group consisting of C1-C18 alkylene, C2-C18 alkenylene, C7-C18 aralkylene, C7-C18 alarylene and C6-C18 arylene; L is a divalent linker joining the blocks; and m and n are each an integer of greater than 1.</p> |
