Abstract: FIELD: polymer production. SUBSTANCE: polyamides are prepared from mixture of at least one lactam and water under polyamide- forming conditions. In the first step, mixture containing 0.5 to 7 wt % water is heated to 220-310 C at pressure allowing reaction mixture to be single-phase and liquid to achieve degree of polymerization at least 85%, after which pressure is adiabatically thrown off and polymerization further proceeds at 215 to 300 C. For example, first-step polycaproamide with molecular weight 3000 to 9000 (on the base of end group content) and polycaproamide with molecular weight 3000 to 14000 are described. High-molecular polycaproamide is prepared by solid-phase polycondensation of low-molecular one upon heating. EFFECT: enhanced process efficiency. 12 cl, 4 tbl, 5 ex

Abstract: The invention relates to a solid formulation of a plant protection agent. Said formulation is obtained by producing a melt containing 1-80 wt. % of an active agent or a combination of active agents which can be used for plant protection; 20-99 wt. % of at least one thermoplastic binder with a melting or glass transition temperature of more than 70~ C, and 0-20 wt. % additives, the sum of all of these constituents equalling 100 wt. %, and then pelleting said melt by reducing it to drops in a first stage and setting the drops by means of cooling in a second stage.
