Abstract

The invention discloses a polymethyl polyglycol methacrylate containing an isosorbide sorbitol ester structure as well as a preparation method and a use method thereof. The preparation method comprises the following steps of: mixing 2-acrylic acid-5-isosorbide dinitrate, methyl acrylate compounds and methylpropenoic polyglycol acid ester compounds; polymerizing free groups under the protection of nitrogen gas; reacting at the temperature of 20-90DEG C for 1-20 hours; repeatedly precipitating and dissolving generated polymerisate by petroleum ether and tetrahydrofuran; and finally, vacuum drying. The obtained polymer has a certain analgesic function and a better anticoagulation effect.

Description

technical field [0001] The present invention relates to polymethylpolyethylene glycol acrylate and its preparation method and application method, in particular polymethylpolyethylene glycol acrylic acid containing sorbitol mononitrate structure used for anticoagulation on the surface of polymers Esters and methods of making and using the same. Background technique [0002] In recent years, the research on the blood compatibility of the surface of biomedical materials used in contact with blood has attracted people's attention and has become a research hotspot. Blood-compatibility means that the material does not cause denaturation of plasma proteins, does not destroy the active ingredients of blood, does not cause blood coagulation and thrombus formation after contact with blood. As early as the 1960s, it was discovered that when biomaterials are implanted into the body and come into contact with blood, protein molecules will be adsorbed on the surface of the material, whic...
