A method of producing polyamide material with peptides is disclosed. The method includes: mixing a peptide material and water to form a peptide solution; mixing caprolactam and the peptide solution to form a first solution; adding a catalyst into the first solution to form a second solution; adding an antioxidant into the second solution to form a third solution; causing a ring-opening reaction in the third solution; heating the third solution to a dehydration temperature to dewater the third solution; forming a polyamide material with peptides.

A process for the production of a polyamide is disclosed. The process for production of a polyamide (P) comprises mixing a first mixture (M1), which comprises at least one lactam and at least one catalyst, with a second mixture (M2), which comprises at least one lactam, at least one activator and at least one amine, to give a polymerizable mixture (pM) and then polymerization of the polymerizable mixture (pM) to give the polyamide (P). A polyamide (P) obtainable by the process of the invention is also disclosed, as well as moldings made of the polyamide (P).

The invention relates to a process for the production of fiber composite materials via specific application of monomer mixtures to a surface of a fiber material and subsequently polymerization.

Process for the production of solid particles comprising a material. with melting point from 20 to 300 C. at atmospheric pressure, characterized in that a mixture comprising:

a1) the material in molten form and

a2) the material in solid form

is mixed by means of an extruder to give a paste, this is forced through a pelletizing die to give strands, and the strands are comminuted.

A use of ansa-metallocene complexes for the polymerisation of cyclic esters and cyclic amides is disclosed. The ansa-metallocene complexes are particularly active as initiators/catalysts in the polymerisation of lactides, with the resulting polymeric material demonstrating low polydispersity.
