The invention is in a conductive prepolymer composition which when polymerized and cured is used to coat a substrate material such as steel, stainless steel, iron, brass, copper, aluminum, platinum, titanium, silver, gold, Telfon, plastics, glass, or combinations thereof. It comprises: (a) from 25 to 99 parts by weight of a poly(amide-imide) prepolymer; (b) from 1 to 25 parts by weight of a trifunctional ester selected from the group consisting of trifunctional methacrylate ester, trifunctional acrylate ester, and mixtures thereof; (c) from 0.5 to 15 parts by weight of an organo-reactive silane consisting of an amino group containing alkoxysilane having the formula NH2(CH2)nSi(OC2H5)3, where n is an integer from 1 to 20; and (d) a conductive additive. The invention also provides polymer coated substrates having a tenaciously bound polymer layer which is corrosion resistant, has advantageous properties of conductivity and can be soldered.
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 power flosser tip incorporating a tooth-whitening coating. The coating is typically abrasive, and whitens teeth by scraping or wearing down hardened plaque or other tooth discolorations. The coating may also whiten teeth through a chemical reaction. The coating may be flavored in order to enhance user enjoyment. The coating is chemically bonded to the flosser tip, and dissolves when in contact with saliva or water at room temperature and pressure.

Germicidal composition for incorporation into polymeric materials molded to form germicidally protected conveyor components used for food handling. Germicidally protected conveyor components are also provided.
摘要:
A solution for forming a graft substrate containing a graft initiator, a catalyst for activating the graft initiator, a polymerizable silicon softener, and at least one additional prepolymer, each of the softener and the prepolymer which includes a functional group for reaction with an activated site on the substrate for grafting thereto and water. The treated fiber exhibits excellent crockfastness, color fastness, and abrasion resistance, strength, and has a soft hand.
摘要:
The present invention relates to a polymeric coating composition for application onto glass substrates for anti-reflective properties. The coating is provided via chemical grafting that involves the use of monomers and/or prepolymers, catalyst, and graft initiator and when applied onto the surface of the glass substrate forms a polymeric film chemically bonded to the glass with excellent adhesion. This coating can reduce the reflectance of the coated glass surface to as close to zero as possible, thus maximizing transmittance and providing resistance to abrasion, water/chemical attack, and UV degradation.
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.
