The present disclosure is directed to resins and to polymers, copolymers, and blends formed therefrom.

A process of oxidizing an alcohol for the production of its corresponding carbonyl compounds is disclosed, wherein the oxidation is performed with oxygen or gases containing oxygen in the presence of a catalyst comprising at least a gold compound and a copper compound. Said alcohol oxidation by gaseous oxidant can achieve a high yield and selectivity with minimized degradation products or waste organic solvents.

The present invention discloses a non-linear PEGylated lipid, including the structure represented by the Formula (1); wherein, B.sub.1 and B.sub.2 are linking bonds or alkylene groups; L.sub.1 and L.sub.2 are linking bonds or divalent linking groups; L.sub.x, Y, and L.sub.d are divalent linking groups; R.sub.1 and R.sub.2 are C.sub.4-50 hydrocarbon groups or C.sub.4-50 residues of hydrocarbon derivative containing 1-4 heteroatoms; X is CH< or

##STR00001##

n.sub.1, n.sub.2, and n.sub.3 are integers in the range of 4-250; T is a terminal group. Compared with linear PEGylated lipids, the non-linear PEGylated lipid provided herein can realize better protective effects toward the modified LNPs. The lipid pharmaceutical composition of the present invention exhibits high efficiency of drug encapsulation, appropriate particle size, non-toxicity, and good stability in serum. The LNP-nucleic acid pharmaceutical composition of the present invention demonstrates an excellent ability to complex with nucleic acids and shows high transfection activity.
