The reference ethylene/propylene
copolymer (EPM, Keltan 1500R, 49 wt % ethylene) and ethylene/vinyl
acetate copolymer (EVM, Levamelt 700, 30 wt % ethylene, M_n = 35 kg/mol, PDI = 9) and the analogous, maleated EPM

provided by ARLANXEO Performance Elastomers. The EPM-g-MA and EVM-g-MA precursors were dried in a vacuum
oven at 175 °C for 1 h to convert any diacid present into the
cyclic anhydride.^{2 (link),17 (link)} Furfurylamine (FFA, Sigma-Aldrich,
≥99%) was freshly distillated before use. 1,1-(Methylenedi-4,1-phenylene)bismaleimide

Table 1 summarizes the constituents of photocurable 5Y-PSZ suspensions with a solid loading of 50 vol% used for manufacturing dental crowns by our DLP process. Unless otherwise notified, all reagents were used as purchased. To obtain reasonably low viscosities at high solid loadings, 1,6-hexanediol diacrylate (HDDA; Sartomer, Exton, PA, USA) and decalin (Sigma Aldrich, St. Louis, MO, USA) were employed as the photopolymerizable monomer and diluent, respectively [26 (link)]. An alkylol-ammonium salt of a copolymer with acidic groups (DISPERBYK-180; BYK-Chemie GmbH, Wesel, Germany) was used as a dispersant. Diphenyl(2,4,6-trimethylbenzoyl) phosphine oxide (TPO; Sigma Aldrich, St. Louis, MO, USA) was used as a photo-initiator.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
