High molecular wegiht polymers, devices and method for making and using same

A compound, comprising one or more units of chemical formula H—Y—C(═Y)—R1-A-R1—C(═Y)—Y—H (Ia), or H—Y—C(═Y)—R1-A-L-A-R1—C(═Y)—Y—H (Ib), wherein each R1 comprises, independently from one another, one or more residue(s) of a diagnostically, traceably, biologically or therapeutically active or activatable agent(s) that is(are) released upon polymer degradation;

• each Y comprises, independently from one another, one or more O, S, NR2, wherein R2 comprises H, linear, branched or cyclic (C1-C30) alkyl, alkenyl, or alkynyl, or aryl, all of which may be substituted with an aliphatic residue that may be further substituted, O, N, S, P or halogen;
• each A, independently from one another, comprises one or more ester, ether, thioether, amide, thioester, azo, carbonate, or thioamide;
• or an oligomer or polymer thereof comprising an effective number of units to attain a molecular weight of up to about 1,500,000;
• the compound, oligomer or polymer having one or more pre-selected characteristics determined by its chemical structure, the characteristic comprising molecular weight, glass transition temperature, adhesiveness, rigidity, flexibility, malleability, resilience, flow, hardness, mechanical strength, fatigue resistance, toughness, elasticity, intrinsic thermogravimetric profile, hydrophobicity, permeability, crystallinity, hydrolytic stability, bulk erosion, or fatigue resistance.
