The invention relates to the use of low levels of aliphatic primary and secondary amines to control air void formation in any polymerization reaction having carbonyl groups, and especially carboxylic acid ester group-containing monomers at a level of at least 10% of total monomer, where the monomer has a peak polymerization exotherm temperature of greater than the boiling point of the monomer. The primary or secondary amines are used in the polymerization mixture at levels of 100 to 5000 ppm, based on the carboxylic acid ester group-containing monomer. It is believed the primary and secondary amines hydrogen bond with the -C=O)O- containing monomer to increase the monomer boiling point, and decrease or even eliminate the formation of air voids due to monomer boiling. The invention is especially useful in polymerization of methymethacrylate polymers and copolymers, either neat, or as a polymer composite system.

This application is a continuation-in-part of U.S. application Ser. No. 13/751,835, filed Jan. 28, 2013.This disclosure relates to a route to non-phthalate, aromatic ester plasticizers.Plasticizers are incorporated into a resin (usually a plastic or elastomer) to increase the flexibility, workability, or distensibility of the resin. The largest use of plasticizers is in the production of “plasticized” or flexible polyvinyl chloride (PVC) products. Typical uses of plasticized PVC include films, sheets, tubing, coated fabrics, wire and cable insulation and jacketing, toys, flooring materials such as vinyl sheet flooring or vinyl floor tiles, adhesives, sealants, inks, and medical products such as blood bags and tubing, and the like.Other polymer systems that use small amounts of plasticizers include polyvinyl butyral, acrylic polymers, nylon, polyolefins, polyurethanes, and certain fluoroplastics. Plasticizers can also be used with rubber (although often these materials fall under the definition of extenders for rubber rather than plasticizers). A listing of the major plasticizers and their compatibilities with different polymer systems is provided in “Plasticizers,” A. D. Godwin, in Applied Polymer Science 21st Century, edited by C. D.

Mixtures of diphosphinic acids and alkylphosphinic acids, a process for preparation thereof and use thereof 120.-. (canceled)2324.-. (canceled) The invention relates to mixtures of at least one diphosphinic acid and at least one alkylphosphinic acid, to a process for preparation thereof and to the use thereof.In the production of printed circuit boards, which are being used to an increasing degree in various devices, for example computers, cameras, cellphones, LCD and TFT screens and other electronic devices, different materials, especially polymers, are being used. These include particularly thermosets, glass fiber-reinforced thermosets and thermoplastics. Owing to their good properties, epoxy resins are used particularly frequently.According to the relevant standards (IPC-4101, Specification for Base Materials for Rigid and Multilayer Printed Boards), these printed circuit boards must be rendered flame-retardant.The thermal expansion of printed circuit boards in the course of production thereof is a problem. The conditions of electronics manufacture for printed circuit boards require that printed circuit boards withstand high thermal stresses without damage or deformation. The application of conductor tracks (lead-free soldering) to printed circuit boards is effected at temperatures up to about 260° C. It is therefore important that printed circuit boards do not warp under thermal stress and the products remain dimensionally stable.Thermal expansion is significant particularly even in the case of prepregs (short form of “preimpregnated fibers”) and laminates, since these constitute the initial forms or precursors of printed circuit boards. It is thus important to minimize the thermal expansion of test specimens in order to obtain a good, dimensionally stable product (for example a finished printed circuit board).It is an object of the present invention to modify polymers for prepregs, printed circuit boards and laminates such that they are subject only to very low ...

Method and apparatus for moldable material for terrestrial, marine, aeronautical and space applications which includes an ability to reflect radio frequency energy and which may be moldable into a parabolic or radio frequency reflector to obviate the need for reflector construction techniques which produce layers susceptible to layer separation and susceptible to fracture under extreme circumstances

Номер: US20210098888A1
Автор: Alexander Socransky
Принадлежит: Individual

The present invention is a unique process of manufacturing rigid members with precise “shape keeping” properties and with reflective properties pertaining to radio frequency energy, so that air, land, sea and space devices or vehicles may be constructed including parabolic reflectors formed without discrete permanent layering. Rather, such parabolic reflectors or similarly, vehicles, may be formed by homogeneous construction where discrete layering is absent, and where energy reflectivity or scattering characteristics are embedded within the homogeneous mixture of carbon nanotubes and associated graphite powders and epoxy, resins and hardeners. The mixture of carbon graphite nanofiber and carbon nanotubes generates higher electrode conductivity and magnetized attraction through molecular polarization. In effect, the rigid members may be tuned based on the application. The combination of these materials creates a unique matrix that is then set in a memory form at a specific temperature, and then applied to various materials through a series of multiple layers, resulting in unparalleled strength and durability.
