Abstract
Impact-resistant polycarbonate and/or polyester carbonate compositions containing at least one oxalate compound selected from the group consisting of metal oxalates, metal hydroxy oxalates, oxalic acid esters and metal salts of oxalic acid esters in quantities of 0.1 to 5 parts by weight (based on 100 parts by weight of the total composition) display an advantageous combination of flow line strength and stress-cracking resistance on exposure to chemicals combined with high thermal stability and good processing properties and they are also flame-resistant.
Claims25
A thermoplastic molding composition comprising poly(ester)carbonate and at least one oxalate compound selected from the group consisting of metal oxalates, metal hydroxyoxalates, oxalic acid esters and metal salts of oxalic acid esters in amounts of 0.5 to 5 parts by weight (based on 100 parts by weight of the total composition).
A method of using an oxalate compound selected from the group consisting of metal oxalates, metal hydroxyoxalates, oxalic acid esters and metal salts of oxalic acid esters comprising incorporating said compound in a molding composition that contains poly(ester)carbonate.
A method of using an oxalate compounds in polycarbonate containing compositions to improve the weld line strength of said compositions.
