Abstract
A continuous process for the production of an oriented high modulus profile is provided together with the novel profiles produced thereby. A dry polymer feedstock is melted and extruded through a die to form a profile precursor having a constant cross-section and specific dimensions. Sequential passage of the profile precursor through roller dies reduces its thickness whilst imparting molecular orientation thereto. The profile is cooled under tension to freeze in the molecular orientation thereof.
