摘要:
Multilayered structures comprising polycarbonate layers and functionalized polyamide layers exhibit adhesion to each other without the use of a tie layer. The multilayered structures are useful in containers requiring the combined properties of high impact strength and chemical resistance and/or oxygen barrier resistance.

摘要:
A reduced fogging impact modified vinyl chloride composition is provided. The composition contains a graft copolymer which is formed by an emulsion process involving grafting a rigid polymeric superstrate to a polyacid surfactant containing rubber. The composition is useful for making molded parts such as automotive dash components, and exhibit reduced level of fogging onto the automotive windshield compared to graft copolymers formed via a process utilizing a linear mono fatty acid.
摘要:
Multilayered containers comprising polycarbonate layers and amorphous polyamide layers wherein the amorphous polyamides are modified and unmodified amorphous polyamides of high glass transition temperatures. The containers have improved stress craze/crack resistance and improved rewashing properties. The containers are useful for carbonated beverages and are rewashable and refillable at elevated temperatures.

摘要:
An amorphous polyamide composition comprising in combination an amorphous polyamide and an aromatic polycarbonate in an amount sufficient to retard crystallization of the amorphous polyamide when exposure to moisture or water particularly at elevated temperatures. The amorphous polyamide composition of the present invention when utilized as one of the layers in a multilayer container provides a container that has improved rewashing cycles.
摘要:
An amorphous polyamide resin is provided having the combined properties of a high glass transition temperature and excellent oxygen barrier properties. The polyamide is obtained from the reaction products of para-xylene diamine, adipic acid and isophthalic acid, and finds particular utility as a container layer for hot fill packaging of fruit juices.
摘要:
An improved asphalt composition is provided with the addition of a graft copolymer resin comprising a rubbery polymeric substrate and a rigid polymeric superstrate. A preferred graft copolymer resin is acrylonitrile-butadiene-styrene copolymer resin. Preferred compositions have increased temperature, range performance and/or decreased penetration values as compared to the same compositions not containing the graft copolymer resins. The asphalt compositions may optionally contain a vulcanized rubber, preferably obtained from scrap tires.
