Aspects concerning the temperature influence on the polymer/polymer interactions between poly(aspartic acid) and poly(ethylene glycol)

▶ Interactions between poly(aspartic acid) and poly(ethylene glycol) are evidenced. ▶ The complexation conditions between polymers were identified. ▶ The interpolymer complex can be used as matrix for bioactive substances. ▶ The interactions were monitored in dilute solutions by determining the zeta potential. ▶ The zeta potential data were sustained by the oscillatory rheology analysis.
