20100009584 | ADHESION ACTIVATOR INTENDED FOR APPLICATION TO A THERMOPLASTIC POLYMER ELASTOMER SUBSTRATE OR PA SUBSTRATE, AND METHODS OF SURFACE TREATMENT AND OF ASSEMBLY BY CORRESPONDING ADHESIVE BONDING - The present invention relates to the assembly by adhesive bonding of a first substrate S1 made of thermoplastic polymer elastomer (abbreviation TPE) or of omopolymeric polyamide (abbreviation PA) or copolymeric polyamide (abbreviation coPA) and of a second substrate S2. The substrates S1 and S2 can be of the same kind, in other words made of TPE or of homopolymeric PA or of coPA, or may be of different kinds. Generally speaking, the thermoplastic polymer elastomer (TPE) substrates S1 are assembled by adhesive bonding with other substrates S2 by means of adhesives or glues based on organic solvent, which are also referred to as two-component solvent-borne polyurethane adhesives. | 01-14-2010 |
20120289652 | SUPRAMOLECULAR POLYMERS AND COMPOSITIONS CONTAINING SAID POLYMERS - Supramolecular polymers having repeat units connected by hydrogen bonds, where the repeat units are monomers, macromers, oligomers or polymers where at least one on the monomers contains at least one 2,5-diketopiperazine group are described. Composition prepared from these supramolecular polymers and articles produced from these compositions are also described. | 11-15-2012 |
20130253115 | HEAT-STABILIZED POLYAMIDE COMPOSITION - A polyamide composition is described that is stabilized with respect to heat. The composition can have a polyhydric alcohol-based stabilization system that is excellent in maintaining mechanical properties after exposure to heat. Also described, is a process for producing these compositions, and the use of these compositions for making various articles. | 09-26-2013 |
20140205783 | Stabilized Polyamide - The present invention relates to the use of a polyhydric alcohol in a polyamide polymerization process for giving the modified polyamide obtained increased stability toward heat, light and/or bad weather. The invention also relates to a polyamide modified in this way, and also to polyamide compositions that may be used for the preparation of specific articles liable to be subjected to high temperatures. | 07-24-2014 |
20140323628 | Stabilized polyamide compositions - The invention relates to a polyamide that is stabilized toward heat, light and/or bad weather by using a compound comprising at least one amine function and at least two aliphatic hydroxyl functions. The stabilizing compound may also be added to the polyamide to form stabilized polyamide compositions. | 10-30-2014 |
20150041138 | NOVEL AGENT FOR INHIBITING THE SWELLING OF CLAYS, COMPOSITIONS COMPRISING SAID AGENT AND METHODS IMPLEMENTING SAID AGENT - The present invention concerns the use of a novel additive as an agent for inhibiting the swelling of clays, in particular in the field of boreholes. More specifically, the present invention concerns the use of a specific diamine and diacid salt as an agent for inhibiting the swelling of clays in an aqueous medium, and a drilling or hydraulic fracturing fluid composition comprising the salt according to the invention and methods for drilling or hydraulic fracturing implementing said salt. | 02-12-2015 |
