The leather industry needs innovative products to meet the continued demands of the global market. To achieve a good performance in the finishing operation, crosslinking of the polymers used in this leather production stage is necessary. These crosslinkers are irritating and harmful.

This study is based on the synthesis of functionalized acryl polymers with epoxy groups to improve the properties of the leather finishing to avoid the use of external crosslinkers, and consequently; harmful products for health and the environment will not be necessary.

Likewise, the affectation in the health of workers exposed to crosslinker has been investigated when the leather finish is carried out. To do this research, a clinical analysis has been carried out prior authorization of the workers.

The study demonstrates a good performance finishing avoiding the use of crosslinkers. In addition, it has been determined that molecular fragments of the decomposition of polyaziridine are present in the urine of one of the employees. Although the human metabolism may metabolize these polyaziridine fragments being non detectable in the urine samples, a positive result was obtained in the analysis by GC-MSD of the urine, and therefore; it could affect the health of this employee.

皮革行业需要创新的产品来满足全球市场的持续需求。为了在涂饰操作中获得良好的性能，该皮革生产阶段中使用的聚合物必须进行交联。这些交联剂具有刺激性和有害性。

这项研究基于具有环氧基的官能化丙烯酸聚合物的合成，以改善皮革涂饰剂的性能，从而避免使用外部交联剂，因此；无需使用对健康和环境有害的产品。

同样，已经在进行皮革涂饰剂时研究了暴露于交联剂的工人对健康的影响。为了进行这项研究，已经在工人的事先授权下进行了临床分析。

研究表明，避免使用交联剂具有良好的性能。另外，已经确定在雇员之一的尿液中存在聚氮丙啶分解的分子片段。尽管人的新陈代谢可能会使尿液样品中无法检测到的这些聚氮丙啶片段代谢，但通过尿液的GC-MSD分析获得了积极的结果，因此；可能会影响该员工的健康。
