This study aimed at determining an optimum polymerization pressure for Polymer Infiltrated Ceramic Network (PICN) blocks by characterizing the conversion degree (DC) and the viscoelastic properties of experimental PICN blocks polymerized at 90 °C under various high pressures followed or not by post-cure treatment (PC). Near infrared analysis and dynamic mechanical analysis were used to characterize DC and viscoelastic properties of sixteen PICN: one control (thermo-cured) and fifteen experimental groups (one thermo-cured followed by PC and fourteen high pressure polymerized PICN, in the range of 50–350 MPa without and with PC). Conversion degree of high pressure polymerized PICN blocks without post curing displays an optimum between 100 and 150 MPa resulting in an improved E′ and T_g. Post curing induces a higher DC with a controversial effect on thermomechanical properties. The results suggested that 100–150 MPa without PC is an optimum polymerization parameter, resulting in PICN blocks with significantly better DC, T_g, E’.

这项研究旨在确定聚合物渗透陶瓷网络（PICN）嵌段的最佳聚合压力，方法是表征在各种高压下（无论是否经过后固化）在90°C下聚合的实验PICN嵌段的转化度（DC）和粘弹性质。治疗（PC）。使用近红外分析和动态力学分析来表征16个PICN的DC和粘弹性：一个对照组（热固化）和15个实验组（一个热固化，然后是PC和14个高压聚合的PICN，范围为50）不带PC时为–350 MPa）。无需后固化的高压聚合PICN嵌段的转化度在100到150 MPa之间显示最佳，从而改善了E'和T _g。后固化引起较高的DC，对热机械性能产生争议。结果表明，没有PC时100-150 MPa是最佳的聚合参数，导致PICN嵌段具有明显更好的DC，T _g和E'。
