Abstract: Cold-pressed mats of lignocellulosic material having a Push Off Test extension equal to at least 85% of that of a mat made with a urea-formaldehyde resin are produced from a lignocellulosic material and binder system. These mats are produced at ambient temperature by separately adding each component of the binder system to the lignocellulosic material, blending the lignocellulosic material and binder system to coat the lignocellulosic material with the binder system, forming the coated lignocellulosic material into the desired form and applying pressure to the formed lignocellulosic material to obtain the desired thickness. The binder system includes: (i) at least one polyfunctional isocyanate and (ii) at least one aqueous dispersion of an adhesive or tackifier.

Abstract: The present invention provides a plastic article containing a first polymer and an interpenetrating network or blend of a second polymer infused in a surface layer of the first polymer, wherein the second polymer is the product of photopolymerizing, in a de-oxygenated environment, a reactive monomer in the presence of one or more radical photoinitiators. The present invention also provides a process for the infusion of a surface layer polymer interpenetrating network (“IPN”) or interpenetrating blend (“IPB”) into plastic articles. By inclusion of a second polymer within the pre-existing first polymer, surface modification of the physical and chemical properties of the host polymer may be enhanced.
