New monomers for fullerene-containing polymers

By reaction of 2-(acryloyloxyethyl) and (undecen-10-en-1-yl) methylmalonates with fullerene C60 in the system toluene-CBr 4-DBU, and also by reaction of 2-(2,2-dichloroacetoxy)ethyl acrylate with C60 in the system toluene-DBU the corresponding products of fullerene monocyclopropanation were synthesized.

Antifouling and biodegradable poly(N-hydroxyethyl acrylamide) (polyHEAA)-based nanogels

We synthesize and characterize two types of poly(N-hydroxyethyl acrylamide) (polyHEAA)-based nanogels: antifouling poly(2-(methacryloyloxy) ethyl trimethyl ammonium-g-N-hydroxyethyl acrylamide) (polyTM-g-HEAA) by a new two-step polymerization method of inverse microemulsion ATRP and surface-initiated atom transfer radical polymerization (SI-ATRP), and pH-responsive biodegradable polyHEAA nanogels by the inverse microemulsion free radical polymerization method. PolyTM-g-HEAA nanogels with a core-shell structure by grafting antifouling polyHEAA onto the cationic polyTM core are tested for their antifouling property and stability in fetal bovine serum (FBS) and nanogels-induced cell toxicity. Results show that with the antifouling protection of polyHEAA, polyTM-g-HEAA nanogels significantly improve their long-term stability in FBS up to 7 days by preventing nonspecific protein adsorption, and they also improve cell viability to ～94% and exhibit almost neglectable cell toxicity. Further, polyHEAA nanogels cross-linked with acid-liable ethylidenebis(oxy-2,1-ethanediyl) ester (EOE) are synthesized, which exhibit both biodegradation and control-release of encapsulated rhodamine 6G (R6G) at acid conditions. Conjugation of transferrin ligands onto R6G-loaded polyHEAA nanogels further enhances cellular uptake efficiency and intracellular drug release for targeting drug delivery. This work demonstrates that polyHEAA-based nanogels with easy synthesis, excellent antifouling property and stability, biodegradability, low toxicity, and pH-responsive intracellular drug release are highly promising for targeted drug delivery systems for biomedical applications.

Method for synthesizing alkyl (meth) acrylate

The invention discloses a synthesis method of alkyl (meth) acrylate, and belongs to the field of organic chemical synthesis. The synthesis method of the present invention employs a heterogeneous solid acid catalyst. The polymerization inhibitor and (meth) acrylic acid were put into the reaction kettle and heated to 50 - 90 °C, and an epoxide was introduced into the reaction kettle for reaction. The reaction solution is filtered to remove the homogeneous solid acid catalyst and the rectification to obtain the target product. The synthesis method not only can improve the selectivity of a target product (methyl) acrylic acid alkyl ester, but also can effectively inhibit the generation of high-boiling-point double esters of by-products generated by the addition of bis (methyl) acrylic acid.
