The present disclosure is directed to certain polyethers copolymers, and polyether derivatives thereof, and methods of making and using the same. For example, the starting materials may include such species as citronellol, geraniol, dihydromyrcene, adipic acid, propanediol, ethylene glycol, glycerol, 1,9-nonanediol, and 1,6-hexanediol.

A process for the purification of crude polyether polyols is provided, wherein the crude polyether polyols are prepared by anionic polymerization of alkylene oxides in the presence of basic catalysts, the process comprising the steps of: neutralization of the catalysts with mineral acid, addition of adsorption agents and/or filter agents and removing the resultant salts and added filter aids by filtration wherein a filter cake is formed, and wherein polyether polyols are recuperated from the filter cake in a subsequent step of pressing the filter cake.

The invention relates to polyethers, polyamines, and polythioethers, as well as to processes for synthesizing them, e.g., using olefins as starting material.

The present disclosure provides compounds of the formula (I): The present disclosure also provides copolymers prepared by polymerizing a first monomer (e.g., dicyclopentadiene) and the compounds. The copolymers may show increased degradability and increased or maintained glass-transition temperature, as compared to homopolymers of the first monomer.

A method of continuously producing a polyol includes: (i) feeding a solid catalyst into a continuous stirred tank reactor (CSTR); (ii) contacting a reaction mixture comprising one or more epoxides and carbon dioxide with the solid catalyst and a chain transfer agent comprising a plurality of sites capable of initiating copolymerization of epoxides and carbon dioxide in the CSTR; (iii) allowing polymerization reaction to proceed until a desired molecular weight polyol has formed; and (iv) terminating the polymerization reaction.

This invention relates to a process for the continuous production of polyether polyols, polyether polyols produced by the inventive continuous process and their use in polyurethane applications.
