Abstract
This paper compares the rheological and adhesive properties of branched oligoester carriers plasticized with the use of various types and concentrations of plasticizers. The oligoesters tested and reported here are star-like branched terpolymers of dipentaerythritol, D,L-lactic acid and glycolic acids, where dipentaerythritol (D) was employed as the branching agent in three concentrations (3%, 5% or 8%) in synthesis by step-by-step polycondenzation.
