摘要:
A formed product having on at least part of its surface an ethylene-vinyl acetate copolymer (EVA) is bonded to an adherend by means of an adhesive containing at least xylene. According to the method of the present invention, the formed product having an ethylene-vinyl acetate copolymer with low adhesion to another substance can be easily bonded to the adherend.

The present invention relates to a solvent-welding process for water-soluble films, characterised in that the solvent has a viscosity of from 1.5 to 15,000 mPa.s.
摘要:
Methods and apparatus are provided for rapidily prototyping a three-dimensional object from a plurality of sequential layers wherein each layer is cut after being fused with a preceding layer. A first sequential layer having a peripheral edge and an exposed face is cut from a first sheet of material using a machine tool path generated from a CAD model of the object. A solvent is then applied to a face of a second sheet of material. The second sheet of material is placed in contacting face-to-face relation with the first sequential layer such that the solvent fuses the face of the second sheet of material with the exposed face of the first sequential layer. A second sequential layer having a peripheral edge and an exposed face is cut from the second sheet of material along a respective machine tool path generated for the second sequential layer. The above procedure is repeated until all remaining layers of the prototype part are produced.
摘要:
A method for increasing the adhesion of a first layer comprising fluoropolymer to a second layer comprising a hydrocarbon polymer is disclosed. The method comprises coating an aliphatic di- or polyamine of less than 1,000 molecular onto at least one of the layers. The resulting multi-layer compositions and articles comprising the composition are also disclosed.
摘要:
A process for purifying fluoropolymers by contacting them at temperatures above 140 DEG C with a liquid perfluorinated cycloalkane. The resulting polymers are particularly useful where polymers with reduced impurities are desirable, such as in medical devices and in parts for the semiconductor manufacturing industry. The liquid perfluorinated cycloalkanes improve the adhesion of fluoropolymer to themselves and other materials.
摘要:
A process for producing vinyl chloride resin products involving the step of adhering vinyl chloride resin members to each other, wherein said step comprises applying to a portion of at least one of said members a compound for vinyl chloride resin capable of dissolving said resin, and bringing the two members into close contact with each other. The use of a compound for vinyl chloride resin showing compatibility with said resin as an adhesive enables the production of safer vinyl chloride resin products than those produced using organic solvents.
摘要:
A method for adhering water soluble polymer films by applying to at least one of the films a solution comprising: (a) from 60 to 90 wt% water, (b) from 10 to 40 wt% isopropanol, and (c) from 0 to 5 wt% polyvalent metal salts.
摘要:
