摘要: 由聚氨酯(PU)预聚物、丙烯酸丁酯和苯乙烯单体的乳液聚合制备了聚氨酯-苯乙烯-丙烯酸酯(PUSA)杂化乳液,¹H NMR显示所得的PU预聚物由烯烃基团封端。TEM表明,其粒径约为150 nm,且为颜色深浅不同的两部分所组成。随着PU含量的降低,杂化乳液的热稳定性增加。DSC分析表明,所得杂化乳液有单一的T_g值,且处于聚氨酯和聚苯丙(PSA)乳液T_g值的中间。当将得到的杂化乳液用于纸塑和塑塑复合时,其剥离强度分别为14.1 N/2.5cm和12.2 N/2.5cm。

Abstract: The polyurethane-styrene-acrylate (PUSA) hybrid latexes were prepared by emulsion polymerization of a mixture of polyurethane (PU) prepolymer,butyl acrylate and styrene monomers. The obtained PU prepolymer was end capped by vinyl groups based on ¹H NMR results. The particles' diameter was about 150 nm from the TEM. The thermostability of the hybrid latexes was improved when the content of PU was decreased,and the single T_g was located between those of PU and polystyrene-acrylate (PSA). When the resultant hybrid latexes were applied in paper-plastic and plastic-plastic laminating adhesives,the peel strengths were 14.1 N/2.5 cm and 12.2 N/2.5 cm, respectively.
