The process can be used to recover scrap or low quaUty resins by using them as the core layer, and using outer layers of virgin resins designed for the specific functional needs of the product such as sHp or gloss and appearance. The inner core may be a foamed resin with surface layers of supedor finish resins. Coextmded films often eliminate the need for cosdy lamination processes. 

A further novel reduced-resin design is the ISEP from Advanced Separation Technologies, Inc. This employs a carousel holding 30 fixed bed columns of resin that continuously rotate to match 20 fixed top and bottom ports. This design also provides for high purity water and reduced regenerant demand and wash volumes, but at a significant capital cost. 

An example of this method of determining e is shown in Figure 3 where the Am has been calculated as a function of e for three HP-LDPE resins, designated LDPE A, B, and C. LDPE A was produced at the highest conversion and LDPE C at the lowest conversion. The SEC data used were obtained at 140°C in 1,2,4-trichlorobenzene. The Mark-Houwink coefficients used for linear polyethylene were K = 5.1 x 10-4 dl/gm and a = 0.706. The 13c NMR Xm values are indic ted by open triangles. 

The chemical industry manufactures and supplies the citizen of the world with thousands of chemicals essential to daily life. The industry product portfolio ranges, for example, from epoxy resins designed for paints protecting concrete or metal, to membranes for water purihcation or pharmaceuticals protecting human life. 

Our results indicate that brassylic acid has potential utility as a monomer for polyester resins designed for industrial coatings.

Although stationary phases were initially made from resins designed to deionise water, the stationary phases presently used are as complex as those found in HPLC. These materials follow the same requirements of microporosity, granular-metric distribution, mechanical resistance and stability under extreme pH conditions.

The generic name hydrocarbon resins designates several families of low molar mass polymers (M from 600 to 104) obtained by polymerization of petroleum, coal tar, and turpentine distillates [80-82], In most cases, these products are obtained by cationic polymerization of mixtures either of aliphatic and/or aromatic mono and diolefins present in the more or less enriched Cs and C9 feedstreams, or of pure aromatic monomers generally of the styrene type. They are complex mixtures of polymers ranging from viscous liquids and tacky fluids to hard, brittle thermoplastics, and are used as additives in adhesives, printing inks, rubbers, coatings, etc. [80-82], They are obviously amorphous and are characterized by their softening point (0 to —150° C), determined by standardized methods (i.e.,... 

There are many ways to fabricate and model viscoelastic polymeric materials [22-32]. Fabrication often involves nonlinear flows that are spatially inhomogeneous, nonisothermal, and temporally complex. The flows also may involve material phase changes, and/or a wide range (1-5 decades) of strains and strain rates. Rheology is often the bridge between resin design and fabrication performance, and remains an active area of research [22]. 

This material is a cyclic methylated high solids resin, designed for stiffness on Nylon and synthetics. This material is viscous in nature, and has extremely good storage stability. Catalysts are required. 

This material is a cyclic methoxylated urea formaldehyde thermosetting resin, designed to supply crease resistance, shrinkage control, in a minimum of stiffness and hand. This material also exhibits excellent stabiltity with prolonged storage, is supplied as a clear colorless thin liquid. Catalysts are required. 

This material is a high solids melamine formaldehyde resin, designed to produce stiffness and excellent durability when applied to various fabrics in a resin finishing bath. This material exhibits good stability up to 90 days, and is supplied as a clear viscous liquid. A catalyst is required.
