摘要:
Novel polyphenylene ether-polyamide compositions having improved compatibility, elongation and impact properties as well as improved processability are prepared comprising one or more polyphenylene ethers, one or more polyamides and a property improving silane derivative compound having in the molecule both (a) at least one silicon bonded to a carbon through an oxygen link and (b) at least one ethylenic carbon-carbon double bond or carbon-carbon triple bond and/or functional group selected from the group consisting of an amine group or a mercepto group, with the proviso that the functional group is not directly bonded to a silicon atom. These compositions may further comprise a polymeric impact modifier therefore and/or an inorganic reinforcing additive and/or other polymers including alkenyl aromatic polymers.

摘要:
A method and system for oxygen molecule scavenging is disclosed. The system employs as a novel terpolymer as the reducing agent for oxygen molecules. The terpolymer is the polymerization product of macrocyclic poly(alkylene dicarboxylate) oligomer, unsaturated functional polymer, and epoxy-functional styrene-acrylate oligomer.
摘要:
A crosslinkable bioplasticizer is disclosed, a mixture of an epoxy-functional bio-derived plasticizer and an aromatic dianhydride. When heated, the mixture crosslinks, which can be accelerated by the addition of a Lewis Acid metal catalyst. The crosslinked bioplasticizer can be melt compounded into a thermoplastic resin or can be formed in situ in the thermoplastic resin. The crosslinking of the bioplasticizer can reduce blooming of the bioplasticizer to the surface of a plastic article made by extrusion, molding, calendering, or thermoforming techniques.
摘要:
A significant disadvantage of the use of polylactic acid (PLA) has been overcome by the use of styrene maleic anhydride copolymer (SMAC) to cause an unexpected increase in the heat deflection temperature of the PLA compound, surpassing a delta improvement of 5° C. over the heat deflection temperature of the PLA alone, at 66 psi as measured using ASTM D648 when the blended compound is essentially dried prior to use. The compound also often exceeds a threshold of 65° C. in heat deflection temperature. Use of a compatibilizer and impact modifier further improves the industrial versatility of the heat resistant PLA compound. Alternatively, use of calcium carbonate in the heat resistant PLA compound also is industrially valuable.
