    摘要: A blend of chlorosulfonated polyethylene (CSPE) and amorphous chlorinated polyethylene (CPE) together with an additive of crystalline thermoplastic polyolefin (e.g., ultralow density polyethlene) is presented. This material is easily processed on the rolls of a rubbermill (i.e., calender) to form continuous sheets of membrane suitable for use in single ply roofing and other similar applications. In a preferred embodiment, a membrane formed from the composition of this invention is used as the upper layer of a multilayer single ply roof.

    摘要: A process for preserving cellular structures includes the steps of pre-treating the structures with a polymeric water solution, drying the structures and then post-treating the structures with an organic solvent, non-water-base solution. Once the structure has been treated with the pre-treatment solution, the specimen is allowed to sit for a predetermined period of time in order for the active ingredients of the solution to penetrate the surface area of the specimen. The specimen is then preferably freeze-dried. The specimens are then treated with a non-water-based post-treatment solution of water-resistant, film-forming polymeric resin to form a barrier coat on the finished product.

    摘要: Low molecular weight olefin resins are blended with small amounts of high molecular weight olefin resins and the blends are chlorinated or chlorosulfonated. Melt and film strengths of the resultant low molecular weight chlorinated and chlorosulfonated resins are thereby increased sufficiently to enable recovery by means of methods which require film or strand formation. The chemical properties and solution characteristics of the blends are substantially maintained compared to those of the low molecular weight chlorinated resins themselves.
