摘要:
The present invention relates to a peelable seal layer formed from blends of polar and non-polar polyolefins, such peelable seal layers being useful for adhering adjacent thermoplastic films together to form a package. Such packaging is easy to open by pulling the adjacent films apart due to the relative ease in rupturing the seal layer.
摘要:
A useful fluorinated polymer as a material for pellicle or the like, which exhibits high durability and transparency to short-wavelength light (ArF excimer laser of 193 nm oscillation wavelength or F2 excimer laser of 157 nm oscillation wavelength). There is provided a pellicle wherein the polymer (I) for use in pellicle film and/or adhesive therefor consists of one essentially having the following unit (1). The unit (1) is one wherein a fluorinated chain constituting a polymer main chain consists of carbon atoms and ether oxygen atoms, and wherein at least one of the main chain constituting carbon atoms is one constituting a cyclic group while at least one of the main chain constituting ether oxygen atoms is one not constituting a cyclic group. For example, the unit (1) is one of the following formula (A1): (A1) (wherein n is 1 or 2; RF1 is -F or -CF3; and RF2 is -F or a C1-C5 perfluoroalkyl).

lonene elastomers are prepared by reaction of polymeric diamines and certain dihalide linking agents. These elastomers have utility in coating compositions, adhesive compositions, and in the fabrication of elastomeric articles. Certain novel dihalide linking agents are also claimed.
摘要:
A composition and adhesive film of a thermosetting resin and a terpolymer of an α-olefin, carbon monoxide and an ethylenically unsaturated carboxylic ester monomer, wherein the melt temperature of the terpolymer is less than the set temperature of the thermosetting resin. The film may be applied to a substrate to provide for an adhesive backing. The film may also be utilized to adhesively bond first and second substrates together.
摘要:
Improved structural adhesive obtainable by a process which comprises subjecting a linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated compound to a heat-treatment for a period sufficient to effect cross-linking in the amorphous phase of the polymer. Process for its preparation by converting a thermoplastic material in a thermosetting material, and laminates prepared with the improved structural adhesive.
摘要:
The object of the present invention is to provide a moisture-curable hot melt adhesive having high initial adhesive strength, long open time, excellent coating property and reduced stringing property. The present invention relates to a moisture-curable hot melt adhesive comprising (A) a urethane prepolymer having a terminal isocyanate group, (B) a metallocene-based polyolefin having a viscosity of 10,000 mPa·s or less at a temperature of 170° C. and (C) a polyester-polyether copolymer.
