This invention provides a method of using perfluoroalkyl hydroxyalkyl siloxanes to impart wash durable soil and stain repellency to a fibrous substrate such as cotton and cotton/polyester fabric.

Fluorosilicone compositions as wash durable soil and stain repellent

Thermoplastic blends of a polyamide having low amine end-group concentration and a polymer containing ester or carbonate linkages. The blends are useful in providing molded parts having improved properties such as improved impact strength.

Thermoplastic blends of a polyamide having low amine end-group

Blocked amine terminated polycarbonate is provided which can be used to form anhydride terminated polycarbonates, or copolymers with various functionalized organic polymers. A blocked amino phenol, such as N-t-butoxycarbonyl tyramine can be used as a chain stopper under interfacial conditions to chain stop polycarbonate. The t-butoxycarbonyl can be removed by melt processing the polycarbonate to yield an amine end group which can be reacted with other polymers or with an organic dianhydride to form anhydride terminated polycarbonate. The anhydride terminated polycarbonates can be used to form copolymers with amine terminated polyamides.

Blocked amine terminated polycarbonates and products obtained therefrom

Triazine compounds are prepared by the reaction of a bisphenol, a monotetrahydropyranyl-protected bisphenol or a hydroxy-terminated polycarbonate with a chlorocyanurate containing epoxy and/or aromatic substituents. The compounds derived from bisphenols or protected bisphenols may be converted to polycarbonates, which form copolymers with other polymers containing acid or amine groups or derivatives thereof.

Triazine derivatives of monomeric and polymeric hydroxy compounds

Triazine compounds are prepared by the reaction of a bisphenol or a hydroxy-terminated polycarbonate with a chlorocyanurate containing epoxy and/or aromatic substituents. The compounds derived from bisphenols or protected bisphenols may be converted to polycarbonates, which form copolymers with other polymers containing acid or amine groups or derivatives thereof.

Copolymer compositions prepared from triazine derivatives of

Branched polycarbonates are prepared by the reaction of at least one polyepoxy compound, preferably triglycidyl isocyanurate, with at least one carboxylic acid-terminated polycarbonate, preferably of the type prepared by employing t-butyl p-hydroxybenzoate as a chainstopper in an interfacial polycarbonate formation reaction followed by thermal elimination of isobutene. The branched polycarbonates have high melt viscosities and high complex viscosity ratios, and are particularly useful in such operations as blow molding.

Poly epoxy branched polycarbonate and method for preparation

Carboxy-functionalized polycarbonates are prepared by incorporating a carboxylic acid-substituted phenol, preferably t-butyl p-hydroxybenzoate, as a chainstopper in a polycarbonate-forming reaction. The products are capable of forming copolymers with other polymers such as polyamides and functionalized olefin polymers, by generation of a carboxy group which reacts therewith.
