WEBROMP of DCPD results in a cross-linked polymer that possesses high notch-impact strength and offers high temperature and corrosion resistant properties as well as high stability versus chemicals. Furthermore, the polymer's surface is quickly oxidized in air and thus a relatively polar surface is generated which can be easily painted.

Polydicyclopentadiene - Wikipedia
WEBPolydicyclopentadiene (PDCPD) is a polymer material which is formed through ring-opening metathesis polymerization [2] (ROMP) of dicyclopentadiene (DCPD). PDCPD exhibits high crosslinking, which grants its properties, such as high impact resistance, good chemical corrosion resistance, and high heat deflection temperature.

WEBNov 10, 2017 · Surface-attached polydicyclopentadiene (pDCPD) films were prepared on gold and silicon substrates via surface-initiated ring-opening metathesis polymerization (SI-ROMP) of dicyclopentadiene (DCPD).
WEBThe mixing of DCPD with Grubbs’ catalyst ini-tiates the ROMP reaction shown in Figure 1. This ROMP reaction can be extremely rapid at room temperature, the speed depending on the catalyst concentration and sample size. The polymeriza-tion of DCPD was accomplished with three differ-ent catalyst/monomer ratios, as shown in Table 1. Technique
