Embodiment 1

[0029] Preparation of olefin-terminated polyarylate: First, add 0.03mol (6.84g) of bisphenol A, 0.066mol (2.64g) of NaOH, 80ml of deionized water and 0.051g of phase transfer catalyst into a three-necked flask, and stir to dissolve bisphenol A It forms an inorganic phase in water. Dissolve 0.015mol (3.03g) of terephthaloyl chloride and isophthaloyl chloride in 150ml of dichloromethane to form an organic phase with a certain concentration. Slowly drop the organic phase into the inorganic phase at a temperature of 10°C. After stirring and reacting for 2 hours, slowly add 0.0035mol (0.317g) of acryloyl chloride monomer dropwise at 10°C. The following reaction was carried out for 1 hour. Remove dichloromethane and water, and obtain terminal olefin-based polyarylate after drying, and use GPC-MwA gel chromatography to measure the number-average molecular weight of polyarylate for 6300.

Abstract

The invention discloses a polysiloxane-polyarylate block copolymer as well as its preparation and application. The polysiloxane-polyarylate block copolymer is shown in the following formula:. The surface of the block copolymer of the invention has low surface energy and strong hydrophobicity; it has an obvious microphase separation structure and has great application value in the field of blood compatibility materials. The preparation process is as follows: using fluorine-containing / fluorine-free olefin-terminated polyarylate and fluorine-containing / fluorine-free hydrogen-terminated polysiloxane as raw materials, using tetrahydrofuran, isopropanol, toluene and benzotrifluoride in One or more than two are solvents; under the action of catalyst 1,3-divinyl-1,1,3,3-tetramethyldisiloxane platinum (0) or chloroplatinic acid, hydrosilylation is added. The synthesis method is simple, the reaction conditions are mild and easy to control, and the industrial production is easy.

Description

technical field [0001] The invention relates to a polysiloxane-polyarylate block copolymer and its preparation and application, belonging to the technical field of block copolymers. Background technique [0002] Due to the existence of two or more monomer segments with different properties in multi-component polymers such as block copolymers, when the monomer segments are incompatible, phase separation tends to occur, forming a scale from nanometer to micron. This kind of phase separation is called microphase separation, and the structure formed by different phase regions is called microphase separation structure (Liu Honglai, Hu Ying, Chinese Journal of Chemical Engineering, 2003, 54:440-443). It is because of these heterogeneous structures that this kind of multi-component polymers has many excellent properties. Existing studies have shown that in the fields of blood compatibility materials, anti-fouling coatings and anti-icing coatings, polymer materials with microphase ...
