Provided is a polyester resin having excellent low-temperature fluidity and storage stability that achieves both dispersibility and grindability. A polyester resin including a sulfonate component and a hetero alicyclic skeleton component as constituent units.

An aqueous binder system including a mixture of urea-formaldehyde resin and water-dispersible polyester resin. A combination of the binder system applied to fiber insulation, a composite glass mat, glass/polyester mat, polyester mat, or substrate of a coated abrasive product. Fiber insulation, a composite glass mat, glass/polyester mat, polyester mat, or coated abrasive product with the binder system including urea-formaldehyde resin and water-dispersible polyester.

An object of the present invention is to provide an aqueous dispersion composition containing polyester resin having high storage stability, film-forming properties, tackiness, adhesiveness, and water resistance. An aqueous dispersion composition containing polyester resin, comprises, a polyester resin (A), a coalescing aid (B), and an aqueous medium (C), wherein the coalescing aid (B) has a Hansen solubility parameter with a dispersion term (d) of 15.4 MPa.sup.0.5 or more and less than 18.0 MPa.sup.0.5, a polarization term (p) of 4.1 MPa.sup.0.5 or more and less than 9.1 MPa.sup.0.5, and a hydrogen bond term (h) of 7.0 MPa.sup.0.5 or more and less than 12.3 MPa.sup.0.5.

The invention provides a polymer system, including a first composition and a second composition. The first composition is different from the second composition. The first composition includes a first gelator, the first gelator including a plurality of acylhydrazine moieties. The second composition includes a second gelator, the second gelator including a plurality of formyl moieties. At least one of the first composition and the second composition includes a prepolymer. The invention further provides a method of using the polymer system to form a polymeric material via multiple stages to more effectively control the rheology of the components over a variety of timescales.
