MOLDING MATERIAL CONTAINING POLYAMINE/POLYAMIDE COPOLYMER, ITS USE AND ARTICLE CONTAINING THE MOLDING MATERIAL |
摘要 |
<p>PROBLEM TO BE SOLVED: To produce a molding material which has better cuttablity and blow moldability than those of conventional polyamide molding materials, and has a high melt rigidity. SOLUTION: The molding material comprises a polyamine/polyamide copolymer to be produced by using (a) 0.05-2.5 mass% (based on the polyamine/ polyamide copolymer) polyamine having at least 4 nitrogen atoms and (b) a polyamide-forming monomer to be selected from an equimolar compound of a lactam, anω-aminocarboxylic acid and/or a diamine and a dicarboxylic acid, and meets the conditions that the viscosity at -250 deg.C is at least 5,000 Pa.s and the shear rate is 0.1 1/s; and the viscosity ratio at -250 deg.C is at least 7 (in this instance the melt viscosities at shear rates of 0.1 1/s and 100 1/s being compared with each other).</p> |
