Waterborne unsaturated polyester resins
Macromolecular Materials and Engineering, 2000 The transformation of solvent soluble unsaturated polyester resins into resins able to form stable water dispersion is presented in this paper. The methods of modification are discussed, consisting of the introduction of polar hydrophilic groups such as carboxylic and sulfonic ones (sodium 5-sulfonatoisophthalic acid) into the resin molecule, which ...

Aging Behavior and Modeling Studies of Unsaturated Polyester Resin and Unsaturated Polyester Resin-Based Blends [PDF]
, 2019 This chapter deals with various cases of degradation of unsaturated polyester resin (UPR)-based materials (composites with polyester matrices and polyester interpenetrated networks). The consequences of degradation mainly on mechanical and engineering properties are presented from a structure-relationships point of view.
