Abstract: In this paper, polyvinyl acetates (PVAcs) were prepared by free radical emulsion polymerisation at room temperature in the presence of persulphate and commercially available reducing agent monomer of 2-(dimethyl amino)ethyl methacrylate (DMAEMA). The molecular weight and the radius of gyration of the PVAcs were analysed by using gel permeation chromatography and dynamic/static light scattering，the storage modulus in a wide and high-frequency range of PVAcs microrheological properties was studied by the diffusive wave spectroscopy (DWS). By adjusting the concentration of persulphate and DMAEMA, Cole-Cole plots were used to demonstrate that a series of branched PVAcs with different branching degree were obtained. The increase of the DMAEMA concentration led to a higher degree of branching, the branched PVAcs showed low storage modulus and lower chain entanglement. The method can synthesise branched polymers through emulsion polymerisation at room temperature, enriching the synthesis of vinyl branched polymers，and offer a promising future for preparing branched vinyl polymers on a large scale and at low cost.
