| 摘要 |
FIELD: manufacturing of heat and sound insulation materials. SUBSTANCE: polymerization of C<SB>6</SB>-C<SB>12</SB> lactams is carried out in the presence of activating agent, catalyst, frothing agent and finely dispersed filler. Toluylene diisocyanate is used as activating agent, sodium formate is used catalyst, product of direct distillation of white spirit having boiling point 165-200 C being used as frothing agent. EFFECT: improved efficiency of the method. 1 tblr
