Improving the physical properties of glass composite polydicyclopentadiene by heat treatment

摘要

A method is disclosed for making a reinforced polymeric structure having enhanced physical properties by polymeriz­ing, in contact with an uncoated, unsized, woven glass fab­ric, a metathesis-polymerizable liquid comprising dicyclo­pentadiene (and optionally one or more other strained ring polycyclic cycloolefins) with which the fabric is saturated, and post-curing the polymerized structure for more than 30 minutes at a temperature greater than about 225°C.
