摘要： UNIFORM, THERMOPLASTIC, NORMALLY SOLID BLENDS CONTAINING CYCLIC ESTER POLYMERS CONTAINING RECURRING UNITS OF THE FORMULA

-(O-(C(-R)2)X-(A)Z-(C(-R)2)Y-CO)-

WHEREIN EACH R, INDIVIDUALLY, IS SELECTED FROM THE CLASS CONSISTING OF HYDROGEN, ALKYL, HALO, AND ALKOXY; A IS THE OXY GROUP; X IS AN INTEGER OF ZERO OR ONE; WITH THE PROVISOS THAT (A) THE SUM OF X+Y+Z IS AT LEAST 4 AND NOT GREATER THAN 7, AND (B) THE TOTAL NUMBER OF R VARIABLES WHICH ARE SUBSTITUENTS OTHER THAN HYDROGEN DOES NOT EXCEED 3, WITH OR WITHOUT RECURRING UNITS OF THE FORMULA

-O-CH(-R'')-CH(-R'')-

WHEREIN EACH R'' IS SELECTED FROM THE CLASS CONSISTING OF, INDIVIDUALLY, HYDROGEN, ALKYL, CYCLOALKYL, ARYL, AND CHLOROALKYL, AND TOGETHER WITH THE ETHYLENE MOIETY OF THE OXYETHYLENE CHAIN OF UNIT II, A SATURATED CYCLOALIPHATIC HYDROCARBON RING HAVING FROM 4 TO 8 CARBON ATOMS, AND THERMOPLASTIC, NORMALLY SOLID POLYMER WHICH CAN BE A CONDENSATION POLYMER, AND/OR AN ADDITION POLYMER OF OLEFINICALLY UNSATURATED MONOMERS HAVING NO MORE THAN ONE HYDROGEN BONDED TO EACH CARBON OF EACH OLEFINICALLY UNSATURATED GROUP THEREOF, INCLUDING SUCH POLYMERS AS CELLULOSE DERIVATIVES, NYLONS, POLYESTER POLYMERS, POLYOXYALKYLENES, POLYCARBONATES. POLY(FLUOROCARBONS), COUMARONE-INDENE RESINS, MALEIC ACID OR ANHYDRIDE ADDITION POLYMERS AND COPOLYMERS, STILBENE ADDITION POLYMERS AND COPOLYMERS, CHLORINATED POLYETHERS, AROMATIC POLY(HYDROXY ETHER) POLYMERS, POLYSULFONES, POLYPEPTIDES, ETC. THESE NOVEL BLENDS ARE USEFUL IN THE PRODUCTION OF FIBERS, FILMS, COATINGS, ADHESIVES, WIRE AND CABLE COATINGS, MOLDING MATERIALS, EXTRUSION MATERIALS, OR SHAPED ARTICLES, HAVING ONE OR MORE UNIQUE PROPERTIES, SUCH AS, DYEABILITY, IMPROVED STRESS CRACK RESISTANCE, IMPROVED OPTICAL PROPERTIES, E.G., IMPROVED HIDING POWER, LOW HAZE, HIGH GLOSS AND/OR HIGH LIGHT TRANSMISSION, IMPROVED PLASTICIZATION, IMPROVED TOUGHNESS, IMPROVED MELT PROCESSABILITY, IMPROVED IMPACT RESISTANCE, AND/OR IMPROVED ABILITY TO DISPERSE ADDITIVES, SUCH AS, FILLERS, COLORING AGENTS, ANTIOXIDANTS, EXTENDERS, ETC.

摘要： Composite articles having at least one solid substrate of such diverse nature as glass, leather, cellulosic solids (including wood, paper, cotton and cellulose derivatives), polyamide solids, polyurethane solids, natural rubber solids, synthetic rubber solids, phenolic resin solids, epoxy resin solids, styrene polymer and copolymer solids and the like, bonded to an adhesive body which is anti-blocking (non-tacky) at ambient temperature but is heat activatable at relatively moderate temperature as low as 60* C. to provide excellent bonding upon cooling to ambient temperatures, and which comprises a cyclic ester polymer having recurring units of the formula:

WHEREIN EACH R'' is selected from the class consisting of, individually, hydrogen, alkyl, cycloalkyl, aryl, and chloroalkyl, and, together with the ethylene moiety of the oxyethylene chain of Unit II, a saturated cycloaliphatic hydrocarbon ring having 4 to 8 carbon atoms. Also novel adhesive compositions containing the above-described cyclic ester polymer and vinyl alkyl ethers in the form of solutions, dispersions, powders, films, coatings and granules or pellets. The invention is applicable to adhering a broad range of diverse types of substrates without the necessity of using high temperatures or long setting times or toxic materials. It is also applicable to the production of heat activatable coatings or seals for diverse packaging materials, laminating uses, construction uses, investment molding type castings, and repair uses.
