Abstract:
Compositions of ethylene/alkyl acrylate blended or grafted with polypropylene are dyeable with disperse or cationic dyes. Compositions of polyolefin, a small amount of polyester and polar material selected from ethylene/alkyl acrylate, maleic anhydride and acrylic acid are also dyeable. A hydrophilic modifier of a monoglyceride and a salt of a linear alkyl phosphate may be included. The compositions are fiber forming.
Abstract:
A resin material provided with softness and good rheological properties, suitable for injection molding, and showing no tackiness is obtained by grafting propylene homo and copolymers with grafting units selected from polyalkenilenes (1 to 30 % by weight) and EP(D)M polymers (5 to 65 % by weight), or mixtures thereof, and optionally with vinyl polybutadiene grafting units (0.01 to 10 % by weight).
Abstract:
Es werden Oligomere oder Polymere Siloxane beschrieben, die der Formel I entsprechen, wenn X ein monovalenter Rest ist, oder die entsprechend vernetzt sind, wenn X ein mehrwertiger Rest ist, und deren wiederkehrende Einheiten statistisch oder in Blöcken angeordnet sind, worin n eine Zahl aus dem Bereich 1-100; m eine Zahl aus dem Bereich 0-100; p eine Zahl aus dem Bereich 0-100 darstellt; A ein Rest der Formel vorzugsweise Trimethylsilyloxy; B ein Rest der Formel vorzugsweise Trimethylsilyl ist; oder die zyklische Verbindungen sind; und worin X ein Chromophor vom Typ Hydroxyphenyl-diaryl-s-triazin ist und die übrigen Symbole die in Anspruch 1 angegebenen Bedeutungen haben.

Abstract:
A process for coating a molded article of a polypropylene resin composition comprising polypropylene (A), a specified ethylene/propylene/diene terpolymer rubber (B), a specified ethylene/propylene copolymer rubber (C) and a specified polyhydroxypolyolefin (D), each in an amount satisfying the following relations: 10 « (B) + (C)/(A) + (B) + (C) « 60 (wt %), 1 « (C)/(B) + (C) « 50 (wt %), 0.5 « (D)/(A) + (B) + (C) + (D) « 10 (wt %) without the necessity for cleaning with an organohalogen solvent, which process comprises conducting priming or plasma treatment followed by topcoating. The molded article thus coated has a tightly adhered coating, a good gasohol resistance and an excellent appearance.
Abstract:
The present invention relates to novel piperidine-triazine compounds containing silane groups of the formula (I)
in which R₁ is a group of the formula
R₇ is e.g. hydrogen, X is e.g. >N-R₁₀ with R₁₀ being C₁-C₄alkyl, R₈ is e.g. a group of the formula
with R₁₁ being hydrogen and Z being as defined for X; Y is e.g. >NH, R₉ is e.g. trimethylene, R₂ is e.g. methyl, ethoxy or OH, R₃ and R₄ are e.g. C₁-C₆alkyl or phenyl, m + n is a number from 1 to 100, n is zero or a number from 1 to 90 and can vary from zero to 90 % of the sum of m + n, R₅ is e.g. ethyl and R₆ is e.g. ethoxy, and, when m + n is a number from 3 to 10, R₅ and R₆ together can also form a direct bond. These compounds are effective as stabilizers for organic materials.
Abstract:
UV stabilized polyphenylene ether polymers and blends thereof are provided by this invention. This is accomplished by bonding UV absorbers directly to the polyphenylene ether chain or by polymerizing monomers to which the UV absorbers are bound.
