摘要:
Crosslinkable aqueous-based coating compositions are described which are covalently bonded to a wooden surface to which they are applied. The compositions contain a crosslinkable polymer, a mono and/or polyethylenically unsaturated monomer which can be graft polymerized onto cellulose molecules present in said wooden surface, a water soluble peroxy free radical polymerization catalyst, a source of cations capable of creating free radical sites in said cellulose molecules and, optionally, a crosslinking agent for said crosslinkable polymer. The coating may be air dried under ambient conditions to provide a crosslinked coating which is chemically bonded to the underlying wooden surface.
摘要:
Coating solution for papermaking fabrics that includes as its primary components polytetrafluoroethylane, urethane copolymer and polyacrylamide. The coating composition is prepared in a solution, coated on the fabric and cured. A fabric thus treated has permanent anti sticking properties against pressure sensitive adhesives, pitch from wood pulp, ink deposition and the like.
摘要:
A chemical composition and method for the production of polyolefins having enhanced flame retardancy and abrasion resistance properties. Additives are covalently bound to substrate polymers by means of a graft polymerization process. Chemical grafting is facilitated by a novel mixture of graft initiating catalyst and substrate monomers.

Disclosed are liquid hydrocarbon fuel concentrates, including low sulfur liquid hydrocarbon fuel concentrates containing at least 5,000 ppm boric acid suspended in the liquid hydrocarbon fuel. The liquid hydrocarbon fuels include gasoline, diesel fuel, aviation fuel, jet fuel, boat or motorcycle fuel. Also disclosed are liquid hydrocarbon fuels compositions formed by diluting the concentrate to form compositions containing only from about 10 ppm to about 50,000 ppm boric acid. Also disclosed are liquid hydrocarbon fuel compositions formed of a reaction product of boric acid having a particle size of about 65 microns or less, associated with a liquid hydrocarbon fuel having a monomer or prepolymer chemically grafted thereon.
摘要:
Dispersions of titanium dioxide pigments with improved long-term resistance to pigment settling and precipitation are disclosed. The pigment dispersions are formed by chemically grafting vinyl and/or acrylic polymers to nitrocellulose in dispersions of nitrocellulose and titanium dioxide pigments. Nitrocellulose forms a loose association with titanium dioxide in dispersion. The chemical grafting improves the precipitation and settling resistance of nitrocellulose, and thus the precipitation and settling resistance of the associated titanium dioxide.

A silicone coating material is operative to graft a silicone polymer coating on an ignition wire. The ignition wire includes an insulated conductor with an inner conductive core and an outer insulating jacket layer which has an outer surface. The silicone coating material is applied to the outer surface of the insulating jacket layer and includes a silicone prepolymer, a coupling agent, a catalyst, and a graft initiator. The graft initiator is operative to prepare the outer surface of the insulating jacket to receive by grafting the coating layer including the silicone prepolymer and the coupling agent, and the catalyst is operative to promote grafting by polymerization of the coating layer.
摘要:
This invention relates to a polymeric composition for application onto Reemay and Satin acetate fabric for laser printability with a high level (90% or greater readability of printed characters, washability and enzyme rejection/retardation. The polymeric composition is applied by chemical grafting that involves the use of monomers/prepolymers, catalyst, graft initiator and other ingredients of the composition. The coating thus developed and subsequently applied to Reemay and Satin acetate fabric allows to undergo graft polymerization thereby forming a polymeric film which is chemically bonded to the fabric substrate with strong adhesion. The chemically grafted fabric is highly durable and permanent in terms of distinct legibility of the printed characters on the substrate after 55 launderings or 25 dry cleanings and has excellent level or enzyme rejection/retardation when the coated fabric with laser printed characters are subjected to an enzyme wash process.

摘要:
A flavored toothpaste composition is bonded to the bristles of a disposable toothbrush by a process which involves the chemical grafting and polymerizing of selected monomers and prepolymers to the bristles via a free radical mechanism. This process locks in the flavor until the produce can be utilized. When the toothpaste is brought into contact with an aqueous medium, such as saliva in the oral cavity, the toothpaste dissolves thereby releasing the desired flavor to the teeth and oral cavity.
摘要:
A solution for forming a graft substrate containing a graft initiator, a catalyst for activating the graft initiator, a first component of water dispersable polymer and a second component of a monomer, each of which includes a functional group for reaction with an activated site on the substrate for grafting thereto and water. A method for grafting at least one of the components to a fiber, yarn or fabric substrate is also disclosed wherein increased flame retarding and yarn integrity is achieved while simultaneously allowing control of fabric porosity. This method does not significantly reduce fabric pliability as compared to uncoated fabric. Furthermore, the graft component may be selectively applied polymer to produce a preferred porosity range or a cutting pattern for the fabric substrate. A fabric, a portion of which includes a graft component or components thereon, forms another embodiment of the invention.
