| 摘要 |
The invention concerns a polymer, chosen from polyamide, polyimide and polyamideimide, obtained through polymerisation of at least one or several alkyl-BHT diamine chosen from methyl-bis hexamethylene triamine, ethyl-bis hexamethylene triamine, n-propyl-bis hexamethylene triamine and/or i-propyl-bis hexamethylene triamine, and one or several polycarboxylic acid, chosen from aliphatic polycarboxylic acids, aryl polycarboxylic acids, alkylaryl polycarboxylic acids and arylalkyi polycarboxylic acids, said polymer comprising a minimum amount of alkyl-BHT diamine of 1 mol % relative to the total mole amount of diamine monomers comprised in the polymer, a composition comprising such a polyamide, a shaped article comprising such a composition or such a polyamide, a powder comprising particles comprising such a polyamide and a method of obtaining a shaped article comprising such a polyamide. |
