Abstract: The present invention is directed to the manufacture of polyols and polyurethanes using thiodialkylene glycols. More particularly, the present invention is directed to the manufacture of rigid polyurethane foam using novel polyols prepared by forming a condensation product of a polyethylene terephthalate with a low molecular weight glycol having a molecular weight of about 500 or less and a thiodialkylene glycol such as thiodiethylene glycol. The present invention is also directed to the use of thiodialkylene glycols as cross linking agents in the preparation of polyurethane foam from condensation products prepared by digesting a polyethylene terephthalate with a polyol having a molecular weight of about 500 or less such as a glycol or a triol.

Abstract: This invention relates to ultraviolet light stabilizing hindered polyoxyalkylene polyamines. The products of the present invention can be utilized as ultraviolet light stabilizers for a wide variety of commercial products such as water base paints, oil base paints, polyethylenes, polypropylenes, polyurethanes, etc. The products have the formula: ##STR1## wherein: R represents an alkylene, alkyl, aralkyl, alkaryl or aryl group containing 1 to 24 carbon atoms,R' represents hydrogen, methyl or ethyl,n represents a number having an average value of 1 to 70, andx represents an integer having a value of 1 to 3.In a modified form of the invention, the products are useful also to inhibit oxidation of such products.

Abstract: This invention relates to water soluble derivatives of polyethylene terephthalate. In another aspect, this invention relates to the conversion of solid, water insoluble polyethylene terephthalates to liquid polymeric water soluble derivatives.

Abstract: Flexible polyurethane foams having improved physical properties are prepared by reacting a polyol with an excess of an aromatic polyisocyanate in the presence of a Condensation Product having the formula: ##STR1## where X represents: ##STR2## z represents NHX or --OCH.sub.2 CH.sub.2 OH, y is a number between 0 and about 4,a+c equal about 2 to 10, andb is a number having a value of about 1 to about 50.

Abstract: A mixture of aromatic polyester polyols useful in preparing rigid foams is described. The polyols are made by first reacting recycled polyethylene terephthalate (PET) scrap with an alkylene glycol to form a reaction product which is then reacted with an alkylene oxide, such as propylene oxide. The resultant mixture of aromatic polyester polyols is a homogeneous liquid which does not precipitate solids upon standing, as do some prior art PET-derived polyols.

Abstract: Terephthalic esters may be made to remain in a liquid form by reacting recycled or scrap polyethylene terephthalate (PET) with diethylene glycol and one or more oxyalkylene glycols and stripping out some of the ethylene glycol present. The mole ratio of glycols to scrap PET should also be greater than 1.2:1. This process keeps any diesters from separating out of the solution as solids. These liquid terephthalic esters are useful as polyol extenders in rigid polyurethane foams and as the sole polyol component in polyisocyanurate foams.

Abstract: This invention concerns an improved process of preparing predominantly linear alcohols which comprises the steps of contacting a mixture of terminal and/or internal olefins and synthesis gas with a catalyst system comprising a ruthenium-containing compound in conjunction with one or more tertiary amine promoters, dispersed in a low melting quaternary phosphonium salt and heating said resultant reaction mixture under a pressure of 100 psi or greater at a temperature of at least 50.degree. C. for a sufficient time to produce said alcohols.

Abstract: This invention concerns a process of preparing alcohols and aldehydes which comprises the steps of contacting a mixture of terminal and/or internal olefins and synthesis gas with a catalyst system comprising a ruthenium-containing compound dispersed in a low melting quaternary phosphonium or ammonium base or salt and heating said resultant reaction mixture under a pressure of 100 psi or greater at a temperature of at least 50.degree. C. for a sufficient time to produce said alcohols and aldehydes.
