Polyester Resin Chemistry

Chapter
Part of the The Development Series book series (POLS, volume 30)

Summary

This chapter reviews recent developments in the processing and formulation of unsaturated polyester resins. Considering the condensation polymer first, refinement of existing production techniques is discussed and the alkylene oxide route to the preparation of polyester resins is compared with the conventional diol based process. New, or relatively new, building blocks which can be used to prepare resins with improved properties are also considered.

Turning to the many additives which can be incorporated to modify the properties of polyester resins, flame retardant formulations are reviewed and efforts to improve the maturation, shrinkage and toughness of moulding compounds are summarised.

A novel polyester cement, curable by the addition of water, an ingenious new foaming system and various formulations that emit less styrene vapour during fabrication than standard grades are further examples of the valuable properties which can be introduced via additives.

Future trends in polyester synthesis are considered.
