polyurethane | isoprene |
(organic chemistry) Any of various polymeric resins containing urethane links; used in very many industrial and domestic applications.
(organic compound) An unsaturated hydrocarbon, C5H8, that is readily polymerized; natural rubber (caoutchouc) is cis-1,4-polyisoprene, and trans-1,4-polyisoprene is present in gutta-percha and balata; it is the structural basis for the terpenes.
