Inhoud: An experimental investigation of comb-like polymers (CP) was conducted in three synthesis steps by using two monomers: ethyl acrylate and methyl acrylate. The synthesis of comb-like homo and copolymers was achieved by using macroinitiators. These compounds imply the formation of hydroxyl terminates polyacrylates (HTP) by a chain transfer reaction. The HTP possessed a broad molecular weight distribution (Mw/Mn = 1.61). The CP was freed of its precursors and its molecular weight distribution was rather narrow (1.31-1.44). In addition, the length and number of the “comb” can be controlled. The products were characterized by UV-VIS, FTIR, Gel Permeation Chromatography (GPC), microRaman Spectroscopy (RS), Differential Scanning Calorimetry (DSC), and hydroxyl number titration. The results show that there are situations where it is possible to produce comb-like polymers of interest with high efficiency.
