1. A poly(lactone) comprising units of formula Iwherein
each b=0 or 1; the molar ratio of w:r:s:t=(0-30):(99.9-2):(0-98):(0-30), wherein
w is the number of post-reacted and post-crosslinked α-methylene lactone repeat units, r is the number of α-methylene lactone repeat units, s is the number of comonomer repeat units, t is the number of crosslinked repeat units, andw+s+t is at least 1; R1, R2, and R3 are each independently a hydrogen or C1-4 alkyl; R4, R5, R6, and R7 are each independently a hydrogen, C1-4 alkyl, or F, wherein F is a functional group that imparts a property to the poly(lactone) I, at least one and no more than two of R4, R5, R6, and R7 are F, and F is the same or different in each instance; Q′ is a C1-30 hydrocarbyl group optionally containing a heteroatom wherein Q′ is covalently bonded to at least a second polymer backbones, wherein the second polymer backbone comprises units of formula I; X is a nucleophile residue; G′ is a single bond to an additional polymer backbone or G is a C1-30 hydrocarbyl group crosslinked with one to five additional polymer backbones, wherein the additional polymer backbone comprises units of formula I; when w>0, the total number of units (w+r+s+t) is 100 or greater, when w=0 and t>0, the total number of units (r+s+t) is 5,000 or greater; when w=0 and t=0, the total number of units is (r+s) is effective to provide a weight average molecular weight of 5,000 or greater. |
