Heterofunctional polyesters

Nanosoft Polymers (NSP) offers high quality heterobifunctional polyesters with high purity and low polydispersity.

NSP’s heterobifunctional polyesters derivatives can be used as crosslinking agents or as spacers between two different chemical entities.

Heterobifunctional PEG derivatives have the following general structure:

                                                 X―polyesters―Y

where X and Y are two different functional or reactive groups.
