A method of preparing polyurethane prepolymer does not require using a toxic isocyanate monomer (manufactured by harmful phosgene) as a raw material. Epoxy resin and carbon dioxide are used as major raw materials to form cyclic carbonates to be reacted with a functional group oligomer, and then amino groups in a hydrophilic (ether group) or hydrophobic (siloxane group) diamine polymer are used for performing a ring-opening polymerization, and the microwave irradiation is used in the ring-opening polymerization to efficiently synthesize the amino-terminated PU prepolymer, and then an acrylic group at an end is added to manufacture an UV cross-linking PU (UV-PU) oligomer which can be coated onto a fabric surface, and the fabric is dried by UV radiation for a surface treatment to form a washing-resisted long lasting hydrophilic or hydrophobic PU fabric.

CYCLIC DYNAMIC POLYUREAS FOR POLYMERIC UREA PROCESSING

Принадлежит:

The present invention relates to a one-component processing method and system for preparing polyurea materials. This method and system involves a polymerization process using cyclic oligomeric polyurea precursors. These cyclic oligomeric precursors have dynamic urea bonds such as hindered urea bonds (HUBs). These cyclic oligomeric precursors exhibit dynamic properties to reversibly dissociate yielding isocyanate and amine components which polymerize to yield the polyureas, such as linear, branched or cross-linked polyureas. This method and system has advantages over conventional methods that utilize two-component systems. Such two-component systems require the segregation of the isocyanate and amine components to prevent premature or too rapid polymerization. The resulting polyureas are useful for a variety of applications including coatings. 2. A cyclic oligomer or polymer according to corresponding to formula (Ia).3.

In one or more embodiments, the present invention provides iodine-functionalized phenylalanine-based poly(ester urea)s (PEUs) (and related methods for their synthesis and use) that are metal free, degradable, radiopaque and suitable for use in surgical implants and other medical devices used within a patient. In one or more embodiment of the present invention 4-Iodo-L-phenylalanine and L-phenylalanine are separately reacted with 1,6-hexanediol to produce two monomers, bis-4-I-L-phenylalanine-1,6-hexanediol-diester (1-IPHE-6 monomer) and bis-L-phenylalanine-1,6-hexanediol-diester (1-PHE-6 monomer). It has been found that by varying the feed ratio of the 1-IPHE-6 and 1-PHE-6 monomers, the copolymer composition may be modulated to predictably create phenylalanine-based PEUs having a wide variation in thermal, mechanical and radiopacity properties. As most medical device procedures require placement verification via fluoroscopic imaging, materials that possess inherent X-ray contrast are valuable for a number of applications. 1.

Embodiments of the invention relate to the synthesis of PEUs carrying pendent “clickable” groups on modified tyrosine amino acids. The pendent species include alkyne, azide, alkene, tyrosine-phenol, and ketone groups. PEUs with Mexceeding 100k Da were obtained via interfacial polycondensation methods and the concentration of pendent groups was varied by copolymerization. The incorporation of derivatizable functionalities is demonstrated using H NMR and UV-Vis spectroscopy methods. Electrospinning was used to fabricate PEU nanofibers with a diameters ranging from 350 nm to 500 nm. The nanofiber matricies possess mechanical strengths suitable for tissue engineering (Young's modulus: 300±45 MPa; tensile stress: 8.5±1.2 MPa).

The invention relates to the field of preparing biodegradable polymer slow/controlled release composite, in particular to a biodegradable polymer slow/controlled release binary composite urea-formaldehyde/poly(butylene succinate) and a biodegradable polymer slow/controlled release ternary nanocomposite urea-formaldehyde/poly(butylene succinate)/potassium dihydrogen phosphate. The following steps are included: uniformly mixing two components poly(butylene succinate) and methylol-urea or three components poly(butylene succinate), methylol-urea and potassium dihydrogen phosphate, and then extruding the resulting mixture by an extruder, and the biodegradable polymer slow/controlled release composite urea-formaldehyde/poly(butylene succinate) containing nutrient N and the biodegradable polymer slow/controlled release nanocomposite urea-formaldehyde/poly(butylene succinate)/potassium dihydrogen phosphate containing nutrients of N, P and K are obtained respectively. As one of the raw materials, methylol-urea, the precursor of urea-formaldehyde, can react by way of melt polycondensation to form urea-formaldehyde macromolecular chains with different polymerization degrees at high temperature in the extruder, which are dispersed among the PBS macromolecular chains, thereby obtaining the composite UF/PBS of the present invention; and the hindering effect of the molecular segments of urea-formaldehyde and poly(butylene succinate) and the hydrogen bond interaction between the components result in that potassium dihydrogen phosphate crystals dissolved in the water produced by the polycondensation reaction are restricted to nanoscale during their precipitation process, so as to prepare nanocomposite UF/PBS/MKP. The prepared composites all have excellent mechanical properties, and can be directly used as a biodegradable polymer slow/controlled release fertilizer, or as a matrix polymer to prepare other types of slow release fertilizers, and the formulae with high PBS contents can ...
