Embodiment 1

[0068] This implementation is used to illustrate the NHC 4 h 7 COO(CH 2 ) 3 NH 2 preparation.

[0069] Put 3-carboxypyrrolidine and 3-aminopropanol in a molar ratio of 1:1 into a three-necked flask, stir and react for 240 minutes at 120°C under nitrogen protection, and wash the filter cake with ethanol for 3 times after suction filtration. Drying at 70 °C gives NHC 4 h 7 COO(CH 2 ) 3 NH 2 .

Embodiment 2

[0071] This implementation is used to illustrate the NHC 4 h 7 COO(CH 2 ) 12 NH 2 preparation.

[0072] Put 3-carboxypyrrolidine and dodecylamine into a three-necked flask at a molar ratio of 1:1, and stir and react for 240 minutes at 120°C under nitrogen protection. After suction filtration, wash the filter cake with ethanol for 3 times. Drying under the hood yields NHC 4 h 7 COO(CH 2 ) 12 NH 2 .

Embodiment 3

[0074] This implementation is used to illustrate the NHC 4 h 6 (OH)COO(CH 2 ) 2 NH 2 Preparation of reactive compatibilizer.

[0075] Put 3-carboxy-2-pyrrolidone and ethanolamine into a three-necked flask at a molar ratio of 1:1, react for 240 minutes at 120°C under nitrogen protection, wash the filter cake with ethanol for 3 times after suction filtration, and dry at 90°C , to get NHC 4 h 6 (OH)COO(CH 2 ) 2 NH 2 .

Abstract

The invention discloses a polycarbonate composition. The composition contains polycarbonate, wherein the composition also contains styrene-acrylonitrile copolymer, graft product of unsaturated acid anhydride and alkyl amine containing at least one primary amino and at least one secondary amino at the same time in a molecule. The invention also provides a polycarbonate composite material, wherein the composite material is a product obtained by the reaction of the polycarbonate composition at the melting temperature, wherein the polycarbonate composition is the polycarbonate composition provided by the invention. By using a reactive compatibilizer, the polycarbonate and the styrene-acrylonitrile copolymer are connected by a chemical bond through the reactive compatibilizer so that the prepared polycarbonate material has good melt flow; and moreover, the polycarbonate provided by the invention has good notch impact strength, bending strength, bending modulus, tensile strength, breaking elongation and solvent resistance.

Description

technical field [0001] The present invention relates to a polycarbonate composition and polycarbonate composites formed from the composition. Background technique [0002] Polycarbonate has excellent impact strength, weather resistance, and surface gloss. It is an engineering plastic and is widely used in the preparation of automotive and electronic parts. However, this kind of hard engineering plastic has the disadvantage of poor fluidity. Even at a high temperature close to the decomposition temperature, it still cannot fully meet the requirements of continuous processing. Excessively high processing temperature will also affect the performance of the product. [0003] In order to improve the processing fluidity of polycarbonate, styrene-acrylonitrile copolymer or thermoplastic polyester is usually added to polycarbonate. Thermoplastic polyester and polycarbonate have good compatibility, but unpredictable transesterification reactions will occur between the two. This rand...
