Process for producing large-size formed articles of modified polyamide. |
摘要 |
<p>Described is a process for producing large-size formed articles of modified polyamide, by polymerisation of a mixture containing, besides the omega-lactam corresponding to the polyamide, the following reagents: a) a polymerization catalyst selected from the alkali metal salts of said omega-lactam; b) a polyoxyalkylene polyamine having a molecular weight ranging from 400 to 5,000 and an amine functionality ranging from 1.9 to 2.5; c) a polyisocyanate activator having all of its isocyanate groups blocked with a lactam; said reagents being introduced, at a temperature of from 105 to 125 DEG C, into a mold heated to 130-170 DEG C.</p> |
