Polyurethane acrylate copolymers (PAC) were synthesized via emulsion polymerization following three step synthesis process using toluene-2,4-diisocyanate, hydroxy terminated poly(caprolactone) diol, 2-hydroxyethylacrylate (HEA) and butyl acrylate (BuA). Structural characteristics of the synthesized polyurethane acrylate copolymer (PAC) were studied using Fourier Transform Infrared (FT-IR) spectrophotometer and are with accordance with the proposed PAC structure. The physicochemical properties such as solid contents (%), tackiness, film appearance and emulsion stability were studied, discussed and co-related with other findings. The plain weave poly-cotton printed fabrics after application of PAC was evaluated applying colorfastness standard test method. The results revealed that emulsion stability is the main controlling factor of the synthesized material in order to get better applications and properties. The emulsion stability of the synthesized material increased with increase in molecular weight of the polycaprolactone diol.
通过乳液聚合，使用甲苯-2,4-二异氰酸酯、端羟基聚己内酯二醇、2-羟乙基丙烯酸酯（HEA）和丙烯酸丁酯（BuA），按照三步合成工艺合成了聚氨酯丙烯酸酯共聚物（PAC）。使用傅里叶变换红外（FT-IR）分光光度计研究了合成的聚氨酯丙烯酸酯共聚物（PAC）的结构特征，与所提出的 PAC 结构相符。研究、讨论了固含量（%）、粘性、薄膜外观和乳液稳定性等物理化学性质，并与其他发现相关联。在应用 PAC 后，对平纹棉涤印花织物进行了评估，应用色牢度标准测试方法。结果表明，乳液稳定性是合成材料的主要控制因素，以获得更好的应用和性能。随着聚己内酯二醇分子量的增加，合成材料的乳液稳定性也随之提高。
