A polymer comprising: a polymeric backbone comprising at least one unit having the structure (I), wherein R-R<4> comprise groups selected from the group consisting of H, C1-C12 alkyl, C6-C18 aryl, C7-C18 aralkyl, C6-C18 cycloalkyl or any of the group consisting of C1-C12 alkyl, C6-C18 aryl, C7-C18 aralkyl, C6-C18 cycloalkyl substituted, within the carbon chain or appended thereto, with one or more heteroatoms; R and R<2> or R and R<4> or R and R<1> or R<2> and R<3> may be joined so that with the carbon atom(s) to which they are attached they together form a saturated, partially unsaturated or unsaturated ring system respectively, may have a pendent group which may incorporate a linker unit, (for example a peptide linkage) or a unit having the structure (I); A comprises a proton donating moiety selected from the group consisting of formula (1). B comprises a hydrolytically labile group and is selected from the group consisting of formula (2), wherein each R<5> is individually selected from the group consisting of H, C1-C12 alkyl, C6-C18 aryl, C7-C18 aralkyl, C6-C18 cycloalkyl; wherein groups A and B are in a cis-configuration about bond Ca-Cb; m is an integer of 0 to 100, n, p and q are each an integer of 0 or 1; Q comprises 1 or more structures selected from the group consisting of formula (3) wherein R<6>-R<11> are individually selected from the same group as defined for group R above and r is an integer between 1 and 5000, preferably 1 to 10, most preferably 1 to 6; methods for the production, and uses thereof. |
