Description
Summary:A new method of synthesis of polyphosphonates, based on transesterification of the short oligomers, ended with the methylphosphonate ester groups, afforded a series of polymers with either hydrophobic or hydrophilic chains. Thus, high-molecular-weight polymers with repeating units of desired length (i.e., (-CH sub(2)-) sub(n)) and a reactive group between them (-OP(H)(O)O-) were prepared. This function was used for further functionalization, and amphiphilic polymers were prepared with, e.g., a hydrophobic main chain and hydrophilic side chains or vice versa. Some of these polymers were shown to be able to self-organize, forming uniform spherical structures.
