[0208]实例

[0209]所使用的材料

[0210]在这些实例中使用的共聚物(PEDEK-PEEK)是衍生自4,4’-二氟二苯甲酮(DFBP)、4,4’-二羟基联苯(也称为双酚)和氢醌的缩聚的共聚物。在聚合中的双酚的总化学计量量内，相对于氢醌部分，该共聚物富含双酚残基部分。PEDEK表示来自双酚与4,4’-二氟二苯甲酮的缩聚的聚合物重复单元。虽然可用于本发明的实践的共聚物(PEDEK-PEEK)可以改变聚合物主链内PEDEK和PEEK重复单元的摩尔比，但是在实例中，使用了具有75-25的PEDEK / PEEK摩尔比的共聚物(以下称为PEDEK-PEEK共聚物)。所述PEDEK-PEEK共聚物具有如根据ASTM D3835使用毛细管流变仪测量的在420℃和1000s-1下400Pa·s的熔体粘度。

[0211]类似的富含PEEK的PEEK-PEDEK共聚物，相对于PEDEK重复单元富含PEEK重复单元，也用于对比实例。以下对比实例中使用的所述富含PEEK的PEEK-PEDEK共聚物(以下称为PEEK-PEDEK共聚物)具有70-30和80-20的PEEK / PEDEK摩尔比以及如根据ASTM D3835使用毛细管流变仪测量的在370℃和1000s-1下分别为200Pa·s和190Pa·s的熔体粘度。

[0212]所使用的聚合物(PPSU)是来自美国索尔维特种聚合物有限责任公司的R-5100NT PPSU天然树脂。这是用于挤出模制和注射模制应用通用目的的标准等级的PPSU。它具有如根据ASTM D1238在365℃下使用熔体指数仪并且使用5.0kg重量所测量的14-20g / 10min的熔体流动速率范围。

[0213]所使用的聚合物(PESU)是来自美国索尔维特种聚合物有限责任公司的A-201NT PESU天然树脂。这是用于挤出模制和注射模制应用通用目的的标准等级的PESU。它具有如根据ASTM D1238在380℃下使用熔体指数仪并且使用2.16kg重量所测量的15-25g / 10min的熔体流动速率范围。

[0214]用于对比实例的聚合物(PSU)是来自美国索尔维特种聚合物有限责任公司的P-1700NT PSU天然树脂。这是用于挤出模制和注射模制应用通用目的的标准等级的PSU。它具有如根据ASTM D1238在343℃下使用熔体指数仪并且使用2.16kg重量所测量的5-9g / ...

Abstract

The present invention relates to a polymer blend based on a PEDEK-PEEK copolymer which effectively provides an excellent combination of improved strength and modulus and improved ductility at high temperatures and is imparted beneficial partial miscibility behavior due to the advantages of the PEDEK-type units in the copolymer (PEDEK-PEEK) and blending with a polyphenylsulfone polymer (PPSU), this is unexpected and advantageous, not only maintaining the similar high temperature resistance of the polymer (PPSU) component, but also avoiding a reduction in phase separation and/or crystallization rate as well as a loss of high temperature performance.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to earlier U.S. Provisional Application No. 62 / 932739, filed November 8, 2019, which is hereby incorporated by reference in its entirety for all purposes. technical field [0003] The present invention relates to novel compositions of polyaryletherketone copolymers and polyphenylsulfone polymers having improved heat resistance and mechanical properties, processes for their manufacture, and their use in various fields such as oil and gas exploration and production. Background technique [0004] Polyaryletherketone materials are known as high-performance plastics with high heat resistance and are used in many industrial applications where resistance to extreme conditions is required. [0005] In particular, oil and gas exploration requires resistance to high temperatures and pressures and the ability to withstand prolonged exposure to aggressive chemicals (including notably brine, hydroc...
