In addition, other additives can be included in the sizing composition such as additional polyester resins, additional coupling agents, thermoplastic polymers, anti-static agents, film-former modifiers, wetting agents, stabilizers and lubricants.Type: GrantFiled: December 29, 1981Date of Patent: January 25, 1983Assignee: PPG Industries, Inc.Inventors: Herbert W. Barch, Carl A. Melle, Donald E. McWilliams, Howard J. Hudson

Patent number: RE31577Abstract: Terminally unsaturated liquid epihalohydrin polymers are produced by polymerizing at least one epihalohydrin using acrylic acid or methacrylic acid as a modifier. The polymerization is conducted in the presence of a catalytic amount of a trialkyl oxonium salt of an HMF.sub.6 acid wherein M is an element selected from the group consisting of phosphorus, arsenic and antimony. The polymers are useful as tougheners for unsaturated polyester resin systems.Type: GrantFiled: June 21, 1983Date of Patent: May 1, 1984Assignee: The B. F. Goodrich CompanyInventor: Changkiu K. Riew
