Abstract:
1. A polymer of the formula: wherein: i is an integer that varies from 1 to an integer less than or equal to 10 which represents the i j is an integer that varies from 1 to an integer less than or equal to 10 which represents the j k is an integer that varies from 0 to an integer less than or equal to 15 which represents the k each x each y p is an integer from 2 to about 4500, which represents the average number of constitutional units in a polymer chain, wherein a constitutional unit is a repeating unit in the polymer chain; M s t v with the proviso that each A each B each C wherein: each R phenyl and or one or more of R bj and R bj′ may form a bridge between the carbon to which it is attached and the adjacent nitrogen, the bridge comprising —CH 2 CH 2 CH 2 —; each R inclusive, and where z is 0, 1, or 2; each R where z is 1 or 2, wherein: at least one R where z is 0, 1, or 2, or at least one R cj is selected from the group consisting of where z is 1 or 2, and allows for tuning of the miscibility and release rate characteristics of the polymer; R w is an integer from 1 to 600, inclusive; R each R
