    • Amino-formaldehyde resins may be prepared using formulations including formaldehyde, glycerin and at least one amino compound selected from the group consisting of urea, melamine, and mixtures thereof; under reaction conditions sufficient to prepare a resin, wherein; the amino-formaldehyde resin is prepared in a substantial absence of a sulfonating agent, ethylene glycol, and polyalkylene glycols. If the amino compound is urea, then the urea is present in a molar ratio of formaldehyde to urea ranging from 0.70 to 1.30; if the amino compound is melamine, then the melamine is present in a molar ratio of formaldehyde to melamine ranging from 1.3 to 2.2; and if the amino compound is a mixture of urea and melamine, then the mixture of urea and melamine is present in a molar ratio of formaldehyde to urea and melamine ranging from 0.35 to 1.3.
    • 可以使用包括甲醛,甘油和至少一种选自脲,三聚氰胺及其混合物的氨基化合物的制剂来制备氨基甲醛树脂; 在足以制备树脂的反应条件下,其中; 基本上不存在磺化剂,乙二醇和聚亚烷基二醇制备氨基甲醛树脂。 如果氨基化合物是尿素,那么尿素以0.70至1.30的甲醛与尿素的摩尔比存在; 如果氨基化合物是三聚氰胺,那么三聚氰胺以甲醛与三聚氰胺的摩尔比在1.3至2.2之间存在; 并且如果氨基化合物是尿素和三聚氰胺的混合物,则尿素和三聚氰胺的混合物以甲醛与尿素和三聚氰胺的摩尔比在0.35至1.3之间存在。
