Abstract
Embodiments include poly(allyl ether)s of polycyclopentadiene polyphenol that can be obtained by allylation of a polycyclopentadiene polyphenol, where the aromatic hydroxyl group(s) (—OH) are converted to HR1C═CR1—CH2—O— and/or H2R1C—CR1═HC—O—, where R1 is as described herein. Embodiments also include thermosettable compositions including the poly(allyl ether)s of polycyclopentadiene polyphenol and products obtained by curing the thermosettable compositions.
Claims15
A poly(allyl ether) of polycyclopentadiene polyphenol of Formula I:
- in which each n independently has a value from zero to 20;
- each m independently has a value of zero to 3;
- p has a value of zero to 20;
- each R is independently a halogen, a nitrile group, a nitro group, an alkyl group, an alkoxy group, an alkenyl group, or an alkenyloxy group, where the alkyl group, the alkoxy group, the alkenyl group, and the alkenyloxy group each independently contain 1 to 6 carbon atoms;
- each Q is independently hydrogen or an alkyl group containing 1 to 6 carbon atoms;
- and each X is independently selected from the group consisting of hydrogen, HR1C═CR1—CH2, and H2R1C—CR1═HC, where each R1 is independently selected from the group consisting of hydrogen and substituted alkyl groups having from 1 to 3 carbon atoms, with the proviso that when each X is hydrogen then at least one R group is selected from the group consisting of HR1C═CR1—CH2 and H2R1C—CR1═HC.
