摘要:
Polymer bonding compositions having greater than about 1 milliequivalent primary amine/100 grams of the polymer, more preferably greater than about 3 milliequivalent non-tertiary amine/100 grams of the polymer. Preferably the polymer is not significantly crosslinked. These bonding compositions may be especially useful for bonding fluropolymers. Processes for making the novel polymers and the resulting multilayer bonded articles are described. The polymers include polymer-bonded ZNHLSi(OP)a(X)3-a-b(Y)b units. The bonding composition may be used for making multi-layer polymer laminates such as tubes and films and containers.

Disclosed are various fluoropolymer blend combinations and multilayer articles comprising a blend in a first layer and a second layer comprising a polymer bonded to the first layer. The invention also provides an article comprising a first layer comprising a blend of two or more fluoropolymers, and a second layer bonded to the first layer, the second layer comprising a partially-fluorinated thermoplastic polymer, a perfluorinated thermoplastic polymer, or a combination thereof. The invention also provides an article comprising a first layer comprising a blend of two or more fluoropolymers, at least one of which comprises a partially-fluorinated thermoplastic polymer, and optionally at least one perhalogenated polymer, and a second layer bonded to the first layer, the second layer comprising an at least partially-fluorinated thermoplastic polymer. The invention also provides processes for preparing blended fluoropolymers and multilayer articles comprising a fluoropolymer layer.

摘要:
Methods for making differentially pattern cured microstructured articles are disclosed, using a molding tool having a microstructured surface, a patterned irradiation to generate irradiate and non-irradiated regions in a radiation curable resin. Different combinations of molding tools and patterned irradiation provide numerous variants of differentially pattern cured microstructured articles without requiring costly modification of the molding tools.

摘要:
Abrasive articles comprising precisely shaped particles are disclosed. The particles are bonded together to form a shaped mass, e.g., a wheel; alternatively, the particles can be bonded to a backing to form a coated abrasive article; or the particles can be bonded into a fibrous, nonwoven substrate to form a non-woven abrasive article.
摘要:
Precisely shaped composites and methods for making these composites are disclosed. The method of this invention comprises the steps of:(a) providing a production tool comprising a plurality of cavities;(b) providing a dispensing means capable of introducing a binder precursor comprising a thermosetting resin into the cavities;(c) providing a means, for at least partially curing the binder precursor;(d) introducing said binder precursor into at least a portion of at least two of the cavities;(e) continuously moving the production tool through a curing zone to at least partially cure the binder precursor;(f) removing the solidified binder from the production tool; and(g) converting the solidified binderinto precisely shaped composites. Steps (f) and (g) can be conducted simultaneously. The composites can be bonded together to form a shaped mass, e.g., a wheel; alternatively, the composites can be bonded to a backing to form a coated abrasive article; or the composites can be bonded into a fibrous, nonwoven substrate to form a non-woven abrasive article.
