Disclosed is a process for manufacturing copolyether ester polyol comprising: (1) providing feedstock comprising polytetramethylene ether glycol having a number average molecular weight of 350 g/mol or less and an oligomeric cyclic ether content of 4.0% by weight or more and a diacid composition selected from alpha-omega alkanedioic acids of formula HO.sub.2C—(CH.sub.2).sub.n—CO.sub.2H, where n is from 2 through 16 to a reaction zone maintained at reaction conditions to produce a crude polyol product; (2) feeding the crude polyol product of step (1) to a separation zone at separation conditions to produce a first separation product having an oligomeric cyclic ether content of 2.0% by weight or greater, and a second separation product comprising copolyether ester polyol having an oligomeric cyclic ether content of less than 2.0% by weight; and (3) recovering the second separation product.

A method for purifying a specific trityl group-containing monodispersed polyethylene glycol from a mixture containing the trityl group-containing monodispersed polyethylene glycol and a specific ditritylated impurity. The method includes performing steps (A), (B) and (C). Step (A): a step of esterifying the hydroxyl group of the trityl group-containing monodispersed polyethylene glycol by a specific method; Step (B): a step of extracting the esterified compound by a specific method; and Step (C): a step of hydrolyzing the esterified compound to obtain the trityl group-containing monodispersed polyethylene glycol.

Functionalized compounds including residues of one or more 1,1-disubstituted alkene compounds. Preferably the functionalized compound includes the residue of two or more 1,1-disubstituted alkene compounds, which are spaced apart. The functionalized compound may be produced by a transesterification reaction. The functionalized compounds may be employed in a polymerizable composition and may be used to prepare new polymers, (for example by reacting the alkene group).

The invention relates to polyoxyalkylenes having pendant long-chain acyloxy radicals and to a process for preparation thereof by an alkoxylation reaction using double metal cyanide (DMC) catalysts.

The present disclosure is based, at least in part, on the discovery that high-purity PEG lipids exhibit superior physical and biological properties, particularly when used in lipid nanoparticle (LNP) formulations. Therefore, the present disclosure provides PEG lipids at a recommended purity, e.g., for use in formulations, such as LNP formulations. The present disclosure also provides LNPs comprising the high-purity PEG lipids, and methods for delivering therapeutic agents to a subject using the same.
