Derivatives of Phenylene-1,2-diamine as Modifiers for Unsaturated Polyester Resins
Abstract:
The results are presented on the synthesis of new modifiers for unsaturated polyester resins, obtained by reacting ethylene oxide or propylene oxide with phenylene-1,2-diamine. The effect of the modifiers and cobalt accelerator on the reactivity of resins was also studied. When used in the amount of up to 1.50 wt.-%, the amines substantially (several times) reduced the gelation time of modified unsaturated polyesters. The reactivity of resins, however, improved on the expense of their stability.

Types of Step-Growth Polymers: Polyesters
Polyesters are commonly prepared from terephthalic acid and ethylene glycol; the crude product is known as poly(ethylene terephthalate) or PET. However, polyesters are synthesized industrially by transesterification of dimethyl terephthalate with ethylene glycol at 150 °C. The two reactants and the polymer...
