Patent number: 6133354Abstract: The present invention teaches a method for enabling the formation of a high damping composition. The method includes mixing a centipede polymer, i.e., a poly(disubstituted ethylene-co-maleimide) polymer, and plasticizers or extenders within a non-vulcanized thermoplastic elastomer to form a relatively high damping gel composition.Type: GrantFiled: November 17, 1998Date of Patent: October 17, 2000Assignee: Bridgestone CorporationInventors: Xiaorong Wang, Victor J. Foltz, David F. Lawson, Naruhiko Mashita
