Abstract
Reactive polymeric compositions are prepared by subjecting arylcyclobutene monomeric compositions to polymerization conditions to provide a partially polymerized composition; and removing the partially polymerized composition from said conditions. The partially polymerized composition can be subsequently subjected to polymerization and curing conditions to provide a cured polymeric composition.
Claims48
A process for preparing reactive polymeric compositions from arylcyclobutene monomeric compositions, wherein an arylcyclobutene is an aryl moiety to which one or more cyclobutene rings are fused, said process comprising
- (a) subjecting the monomeric composition to polymerization conditions to provide a partially polymerized composition, and
- (b) removing the partially polymerized composition from said conditions.
A method for preparing fibers from arylcyclobutene monomeric compositions, wherein an arylcyclobutene moiety is an aryl moiety to which one or more cyclobutene rings are fused, the method comprising
- (a) subjecting the monomeric composition to polymerization conditions to provide a partially polymerized composition in the form of a liquid having an effective viscosity,
- (b) drawing said viscous liquid into strands, and
- (c) subjecting said strands to polymerization and curing conditions.
