New thermal-latent metal catalyst such as tetrakis (lauorate) titanium (LPTi) was designed and synthesized based on a lauroyl peroxide and titanium. The synthetic method is simple with one step reaction. LPTi structure was confirmed by FT-IR analysis, also nano-sized structure of LPTi confirmed using SEM-EDX. LPTi is thermal-latent metal catalyst including titanium that not only promotes urethane synthesis reaction but also increases the dissociation rate of blocked isocyanate. As a result of quantitative analysis of NCO (%) through back titration, when LPTi was added, NCO (%) increased from 2.34% to 3.24%. LPTi can be used as an excellent catalyst for urethane reaction by reducing the polymerization time by about 30% compared to no catalyst. LPTi can be applied to the electronic polymer synthesis.
新型热潜伏金属催化剂，如四（月桂酸酯）钛（LPTi），是基于过氧月桂酸酯和钛设计和合成的。其合成方法简单，仅需一步反应。LPTi 的结构通过傅里叶变换红外分析得到了确认，同时 LPTi 的纳米结构也通过扫描电子显微镜-能谱分析得到了确认。LPTi 是一种热潜伏金属催化剂，其中包含的钛不仅能促进聚氨酯合成反应，还能提高封闭异氰酸酯的离解速率。通过返滴定定量分析 NCO（%），当加入 LPTi 时，NCO（%）从 2.34%增加到 3.24%。与无催化剂相比，LPTi 通过将聚合时间缩短约 30%，可用作优异的聚氨酯反应催化剂。LPTi 可应用于电子聚合物的合成。
