摘要:
Disclosed are processes to prepare monocarboxylic acid esters (mono- and/or diesters) of polytrimethylene ether glycol that are substantially free of residues from the catalyst used to produce the polytrimethylene ether glycol esters, as well as methods for their preparation and end uses thereof. The esters, such as the bis-2-ethylhexanoate esters, have uses as functional fluids.
摘要:
Novel (meth)acrylic ester of poly(trimethylene ether) glycol compositions are provided. The compositions comprise an ester (a monoester, a diester or mixtures thereof) of a polytrimethylene ether glycol and at least one polymerization inhibitor.
摘要:
Disclosed is branched poly(trimethylene ether) polyols prepared from the acid catalyzed polycondensation reaction of 1,3-propanediol, and at least one triol comonomer selected from 1,1,1-tris(hydroxymethyl) ethane and 1,1,1-tris(hydroxymethyl) propane. Also disclosed is a branched poly(trimethylene ether) polyol with an equivalent hydroxyl functionality of about 2.1 to about 3.2 and a Mn of about 200 to about 6000. The polyols are useful in the preparation of polyurethane rigid and flexible foams.

摘要:
Provided are methods for extracting flavor and fragrance materials from natural plant materials, using poly(trimethylene ether) glycol homopolymers and copolymers. The poly(trimethylene ether) glycol homopolymers and copolymers act as solubilizers for essential oils, and can be used to provide compositions having a variety of uses in applications such as cosmetics, personal care products, and industrial cleaning products.
摘要:
Disclosed are antimicrobial compositions, and methods for killing, inhibiting, or preventing the growth of microbes, using trimethylene glycol oligomers or dimers. The trimethylene glycol oligomers and dimers have the formula R(CH2CH2CH2—O—CH2CH2CH2)nR1 where R and R1 are hydroxyl, amine, or ester functionalitiess, and n is 2 or higher. The antimicrobial compositions are useful in personal care and cosmetic compositions
