Abstract: An improved method of making an ethylene acrylate (AEM) elastomer or a polyacrylate (ACM) elastomer wherein an aqueous solution of hexamethylene diamine (HMDA) is employed as the curative agent rather than hexamethylene diamine carbamate (HMDAC). The HMDA reacts with the curative-site monomer derived from the monoalkyl ester of a 1,4-butene-dioic acid in the presence of water, producing (i.e., after press-curing and any secondary heat-curing) a crosslinked elastomer with properties essentially indistinguishable from that produced using HMDAC as the curative agent. Advantageously, the aqueous solution of HMDA can be blended directly into the compound or it can be deposited on an additive such as silica or carbon black prior to blending. Elastomers produced by the improved method according to the present invention are particularly useful in automotive applications requiring oil resistant compositions.

Abstract: Multilayer articles, particularly multilayer articles having electrical or ionic conductivity, are made using an improved melt extrusion process. The process includes a combination step in which a macroscopically homogeneous mass is formed prior to introduction into an extruder.

Abstract: A method of transferring a gene to vertebrate cells is disclosed. The method comprises the steps of: (a) providing microprojectiles, the microprojectiles carrying polynucleic acid sequences, the sequences comprising, in the 5′ to 3′ direction, a regulatory sequence operable in the tissue cells and a gene positioned downstream of the regulatory sequence and under the transcriptional control thereof; and (b) accelerating the microprojectiles at the cells, with the microprojectiles contacting the cells at a speed sufficient to penetrate the cells and deposit the polynucleic acid sequences therein. Preferably, the target cells reside in situ in the animal subject when they are transformed. Preferred target cells are dermis or hypodermis cells, and preferred genes for insertion into the target cells are genes which code for proteins or peptides which produce a physiological response in the animal subject.

Abstract: The present invention relates to an improved catalyst for the selective synthesis of monomethylamine (MMA) and dimethylamine (DMA) at the expense of trimethylamine (TMA) for a starting feed of methanol and/or dimethyl ether and ammonia. The current industrial catalyst for this process is a standard SiO.sub.2 /Al.sub.2 O.sub.3 material. The present invention combines this standard catalyst with microporous carbon molecular sieves (CMS) to form a composite material (i.e., a CMS/SiO.sub.2 /Al.sub.2 O.sub.3 material) with higher selectivity for the desired products MMA and DMA. The invention also relates to methods of making the improved catalyst and a process of using the improved catalyst material in the production of MMA and DMA.
