Functionalized low molecular weight sterically encumbered oligomers

Low molecular weight, high Tg resins, with applications including tire additives and adhesives. An oligomer is obtained by ring opening metathesis polymerization (ROMP) of a sterically encumbered cyclic monomer with an olefinic chain transfer agent. The sterically encumbered cyclic monomer and the o...

Zusammenfassung:Low molecular weight, high Tg resins, with applications including tire additives and adhesives. An oligomer is obtained by ring opening metathesis polymerization (ROMP) of a sterically encumbered cyclic monomer with an olefinic chain transfer agent. The sterically encumbered cyclic monomer and the olefinic chain transfer agent are present in the polymerization at a molar ratio of from 2:1 to about 40:1. Also, methods for making the oligomer by ROMP.
