The synthesis and polymerization chemistry of 1, l-bis (XCHz) cyclopropane (1, X= OH; 4, X= I) was studied. Treatment of 1 with base in the presence of a, o-dihalides did not produce a polyether. However, treatment of 4 with the bis (alkoxide1 derived from hexanediol afforded a polyether of low molecular weight (Mn= 3000, PD= 3). Ageneral method for alkylating norbomadiene in the 2-position was developed. Treatment of norbornadiene with tert- ...
