Abstract
The invention provides certain polyesteramide compositions which have glass transition temperatures (Tg) of greater than or equal to 0° C. The polyesteramides of the invention are useful as polymeric interlayers for laminate structures, for example, safety glass, where excellent toughness is combined with high adhesion to glass.
Claims19
A polyesteramide composition comprising residues of:
- a. at least one diacid;
- b. about 10 to about 90 mole percent of a diol;
- c. about 10 to about 90 mole percent of a diamine;
- and optionally
- d. a multifunctional reactant having at least three functional groups chosen from carboxylic acid, amine, and hydroxyl groups;
- wherein the sum of diacid equivalents is about 100 mole percent and the sum of diol and diamine equivalents is about 100 mole percent;
- and
- e. about 0.01 to about 10 weight percent, based on the total weight of the polyesteramide comprised of a., b., c., and optionally d., of a chain extender reactive with groups chosen from carboxyl, amino, and hydroxyl groups,
- and wherein said polyesteramide exhibits an inherent viscosity of about 0.6 to about 2.0 dL/g.

- e. about 0.01 to about 10 weight percent, based on the total weight of the polyesteramide composition comprised of a., b., c., and optionally d., of a chain extender reactive with groups chosen from carboxyl, amino, and hydroxyl groups,
- wherein said polyesteramide exhibits an inherent viscosity of about 0.6 to about 2.0 dL/g;
- and
- a second layer comprising a polymer composition which is different than the polyesteramide composition of the first layer.
