Special grades of glycidyl ether epoxies have been made with components such as glycerol, polyglycols, pentaerythritol, and cashew nut oil. Other epoxy-polyglycidol resins have been produced from the reaction of epichlorohydrin and polyester polyol based on... [Pg.34]

The polyesters derived from AA and DEG, and from AA and PG are liquid at room temperature. The branched polyesters based on AA-DEG/TMP or AA-DEG/glycerol are also liquid. The polyesters derived from AA-EG, AA-D, AA-HD and AA-NPG are solid at room temperature. It is very interesting that some polyester polyols based on AA and a mixture of... [Pg.269]

As a possible application of glycerol-based polyesters, new crosshnkable polyesters were synthesized via a lipase CA-catalyzed polymerization of divinyl sebacate and glycerol, in the presence of unsaturated higher fatty acids derived from renewable plant oils [110, 111]. The curing of the polymer obtained from hnoleic or hnolenic acid proceeded via a cobalt naphthenate catalyst or thermal treatment to produce a crosshnked transparent fUm with good biodegradabiHty. [Pg.693]

Polyesters [2] find use in fibers [poly(ethylene terephthalate), poly(ethylene oxybenzoate), poly(ester ethers), poly(ester amides), etc.] [1], coatings (especially unsaturated polyesters) [4], plasticizers, adhesives, polyurethane base resins, films, etc. Cross-linked polyesters prepared from glycerol and phthalic anhydride (alkyd resins) have been reviewed [20], High-melting poly aryl esters have been investigated for high-temperature applications. [Pg.54]

By using, together with a diol, a triol such as TMP or glycerol it is possible to obtain polyesters with a functionality (f) higher than 2 OH groups/mol, situated in the range of 2-3 OH groups/mol. These polyester polyols are used for flexible PU foam fabrication. Flexible PU foams based on polyester polyols have a unique property their clickability (capacity to be easily cut) and are used in laminates for textile industry. [Pg.268]

Thus, the polyol nature has a marked effect on the fire resistance, which is in fact the order of thermostability. The most thermostable polyols lead to polyurethanes with improved fire resistance. Thus, polyesters are superior to polyethers in so far as the fire resistance of the resulting polyurethanes is concerned. Cycloaliphatic polyols (for example polyols based on carbohydrates, such as sucrose or alkyl glucosides) produce polyurethanes with superior fire resistance as compared to the simple aliphatic polyols (for example polyether based on glycerol or on pentaerythritol). [Pg.548]
