Dielectric materials with optimal mechanical properties for use in laser ablation patterning are proposed. These materials include a polymer selected from the group consisting of polyureas, polyurethane, and polyacylhydrazones. New methods to prepare suitable polyacylhydrazones are also provided. Those methods involve mild conditions and result in a soluble polymer that is stable at room temperature and can be incorporated into formulations that can be coated onto microelectronic substrates. The dielectric materials exhibit high elongation, low CTE, low cure temperature, and leave little to no debris post-ablation.

Formaldehyde-free binder compositions are described that include an aldehyde or ketone, a reaction product between a polyamine and an organic anhydride, and an acidic compound. The acidic compound may be an organic acid, an acidic catalyst, or both. The acidic compound is supplied in quantities that lower the pH of the binder composition to about 5 or less. The binder compositions may be used in methods of binding fiberglass and the resulting fiberglass products have an improved tensile strength due to the addition of the acidic compound.

A copolymer latex for sealant. The said composition may be used in various applications such as non-pigmented and pigmented sealants for gap filling, waterproofing, in construction and other applications. The copolymer latex composition includes an organic acid fraction, an amide derivative fraction, an acrylic monomer fraction, and a surfactant fraction. The copolymer latex composition may include at least 55% solids of polymerization product of one or more monomers. The said composition is such that the copolymer latex shows properties such as self-thickening ability and good water repellence. The said composition at dry film thickness of about 2 mm provides transparency. In addition, the copolymer latex provides properties like hydrophobicity, tensile strength, elongation efficiency, and low foaming.
