Starch nanoparticle (SNP)‐based pressure sensitive adhesives (PSAs) with core‐shell particle morphology (starch nanoparticle core/acrylic polymer shell) are produced via seeded, semi‐batch emulsion polymerization at 15 wt% SNP loading (relative to total polymer weight) and 40 wt% latex solids. Crosslinker and chain transfer agent (CTA) are introduced to the acrylic shell polymer formulation at a range of concentrations according to a 3² factorial design to tailor the latex and adhesive properties of SNP‐based latexes. The crosslinker and CTA show no significant effect on polymerization kinetics, particle size, and viscosity. Latex gel content is predicted using an empirical model, which is a function of crosslinker and CTA concentration. Both the gel content and glass transition temperature strongly affect the adhesive properties (tack, peel strength, and shear strength) of the SNP‐based latex films. 3D response surfaces for the adhesive properties are constructed to facilitate the design of SNP‐based PSAs with desired properties.

基于淀粉纳米颗粒的压敏胶粘剂的胶粘剂和乳胶性能的修改

具有核-壳颗粒形态（淀粉纳米颗粒核/丙烯酸聚合物壳）的基于淀粉纳米颗粒（SNP）的压敏胶粘剂（PSA）是通过以15 wt％SNP含量（相对于总聚合物重量）进行种子，半间歇乳液聚合生产的）和40 wt％的乳胶固体。交联剂和链转移剂（CTA）以3 ²的浓度范围引入丙烯酸壳聚合物配方中因子设计，以定制基于SNP的乳胶的乳胶和粘合性能。交联剂和CTA对聚合动力学，粒度和粘度没有明显影响。使用经验模型预测乳胶的含量，该模型是交联剂和CTA浓度的函数。凝胶含量和玻璃化转变温度都强烈影响基于SNP的乳胶薄膜的粘合性能（粘性，剥离强度和剪切强度）。构造具有粘合特性的3D响应面，以方便设计具有所需特性的基于SNP的PSA。
