    摘要： The present invention provides new linear phosphorus- and halogen-containing flame retardant polyester additives for normally flammable polymers and coatings for normally flammable natural and synthetic films and fibers, for instance, polyester and cellulose ester films and fibers. The phosphorus- and halogen-containing polymers of the invention are water dispersible or can be rendered water-soluble. They can be prepared by reacting a phosphorus acid reactant such as phosphoric acid with at least one halogenated difunctional monomer. The water-soluble polyesters can be cross-linked to render them insoluble in water by heating together with a methylol compound.Said halogenated monomer is preferably an oxyalkylated diacid or diol and said halogen is attached either on one or more aromatic rings or on a cycloaliphatic ring. The halogenated diols useful in preparing the flame-retardant polymer additives of the invention are selected from the group consisting of at least one of the halogenated, saturated diols having the formula: ##STR1## wherein m and p are integers of 2 to 6; n and q in formulas A, C, and D are 0 or integers of 1 to 10 and integers of 1-10 in formula B; wherein in formulas A-C, X which is attached to an aromatic ring represents 1 to 4 halogen atoms; and wherein in formula D, X represents 1 to 2 halogen atoms and Z is hydrogen, a C.sub.1 -C.sub.6 alkyl radical, or phenyl.Polymer fibers and films such as those made from polyethylene terephthalate and cellulose ester fibers and films such as those prepared from cellulose acetate and cellulose triacetate, each containing a flame-retardant amount of the phosphorus- and halogen-containing flame-retardant polymer additives of the invention are resistant to loss of the polymeric flame-retardant additives of the invention during use.

    摘要： There are disclosed block copolymer lubricants for synthetic textile fibers which are compounds derived from tetramethylene oxide (tetrahydrofuran) and ethylene oxide of the formula:Y--(CH.sub.2 --CH.sub.2 --CH.sub.2 --CH.sub.2 --O--)--(C.sub.2 H.sub.4 O)--H].sub.xwherein Y is the residue formed by the removal of x atoms of active hydrogen from an initiator having a total of not more than 20 carbon atoms and free of elements other than carbon, hydrogen, and oxygen, preferably said initiator is selected from the group consisting of water, alkylene glycols, polyalkylene glycols, alkanols, phenols, and alkyl phenols; x is an integer of 1 to about 5; n is an integer such that the total tetramethylene oxide residue weight, n x, is about 90 to about 10 percent by weight of the total ethylene oxide residue weight; m is an integer such that the ethylene oxide weight, m x, is about 10 to about 90 percent by weight of the total oxyalkylene weight; and the molecular weight of the tetramethylene oxide residue, n x, is about 500 to about 6000. The block copolymer fiber lubricants of the invention are especially useful as lubricants for synthetic fibers such as polyester, polyamide, polyacrylic fibers and mixtures thereof. The fiber lubricants of the invention generally have unexpectedly superior lubricity and oxidation stability in comparison with the ethoxylated polypropylene glycol block copolymer fiber lubricants of the prior art.

    摘要： Lubricants and processing aids for synthetic fibers, particularly polyester and nylon fibers, are disclosed comprising compounds having the structural formulas: ##STR1## and ##STR2## in which R is an aliphatic group generally having about 3 to about 22 carbon atoms; A is a mixture of residues from ethylene oxide and at least one other lower alkylene oxide, preferably a heteric mixture of oxyethylene and oxypropylene residues in the respective ratio by weight of 20:80 to 90:10; and n has a value to produce a molecular weight of about 300 to about 3000.Where liquid products are desired which contain the higher numbered carbon chain residues, low viscosity compounds can be obtained by oxyalkylating a glycerol-1,3-dialkylether with a mixture of ethylene oxide and 1,2-propylene oxide in the respective ratio as set forth above. Thus it is possible by properly balancing the carbon chain length of the R groups in the lubricant compounds of the invention with the oxyalkylene chain length to obtain products varying between water insoluble and water soluble. The oxyalkylated fiber lubricants of the invention have the properties of viscous liquids, solids or pastes at ambient temperature.
