Abstract Compositions comprising macrocyclic, oligomers linear polymers having the same units as said macrocyclic oligomers, fibers and macrocyclic oligomer polymerization catalysts having a viscosity in the range of about 100-1200 poise at the molding temperature may be compression molded at pressures in the range of about 0.5- 7.0 MPa. Molding under these conditions is particularly useful for the formation of large parts.

Why it's free to use
- Filed October 14, 1993. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 14, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 14, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
