Compositions of polyamide resin moldable to blow, blow molded articles and process for the production of an article of polyamide moulded the breath

摘要

"Compositions of polyamide resin blow moldable.Blow molded articles and process for the production of an article of polyamide moulded the breath "is about the compositions of polyamide resin with high temperature for blow molding and articles molThe wind data of such compositions. The blow molded articles exhibit excellent heat resistance, chemical resistance, and dimensional stability.The composition has a melting point of at least 2750c and a glass transition temperature of at least 60 C.The composition comprises an aromatic polyamide, an impact modifier, and a stabilizer.The aromatic polyamide is a polymer or a copolymer which has repeat units derived from a carboxylic acid component and an aliphatic diamine component.In which the carboxylic acid component is terephthalic acid or a mixture of terephthalic acid and one or more other carboxylic acids.And the component of aliphatic diamine hexamethylene diamine or is a mixture of hexamethylene diamine and 2 - methyl -- diamine or 2-ethyl tetrametileno diamine.The impact modifier is selected from the group of (I) polymers and copolymers of ethylene grafted with carboxylic acid, an anhydride thereof,Maleimida or an epoxy compound; (II) thermo polymers and ionu00f3meros of olefin / acrylic acid / anhydride; and (III) thermoplastic elastomers styrene grafted with an anhydride of a carboxylic acid.The stabilizer is selected from the group of (I) a phosphite stabilizers and fosfonito; (II) stabilizers of phenol hindered amine stabilizers; (III) prevented; and (IV) amine stabilizers AROMATH.
