摘要:
Security films that are useful for pharmaceutical packaging. In particular, anti-counterfeiting security films having a luminescent composition on or in a fluoropolymer layer, which luminescent composition luminesces upon the application of ultraviolet radiation in the 200 nm to 300 nm range, in which the luminescent component is optionally and preferably not viewable to the unaided eye. The films are particularly useful for the formation of anti-counterfeiting blister packaging in compliance with FDA regulations.
摘要:
Hot melt adhesive compositions which have enhanced adhesion to difficult substrates, particularly at refrigerator/freezer temperatures or at elevated temperatures. The inventive compositions require a base polymer comprising at least one metallocene ethylene-containing polymer or at least one non-metallocene, amorphous, propylene containing polymer; a tackifier; an optional wax; and an adhesion promoting additive comprising at least one semi-crystalline polymer having a weight average molecular weight of about 30,000 daltons or less. It has been found that the adhesion promoting additive of this invention enhances the adhesion properties of a hot melt adhesive composition having a metallocene ethylene-containing base polymer or non-metallocene, amorphous, propylene containing base polymer, particularly at elevated temperatures or at low refrigerator and freezer temperatures where other conventional adhesives have been unsuccessful.
摘要:
An improved coating composition having one or more polymeric binders dispersed in a liquid medium, wherein the improvement comprises an anti-sag and anti-settling effective amount of a copolymer comprising a polymeric backbone comprising recurring monomeric units derived from monomers selected from the group consisting of one or more .alpha.-olefins and one or more unsaturated carboxylic acids, said backbone having grafted thereto, by a covalent amide linkage, one or more polymeric grafts comprising at least one recurring monomeric unit selected from the group consisting of: --NHC(O)RC(O)NHR.sup.1 and --NH--R--C(O)-- or a combination thereof, wherein R is an alkylene group of at least about 2 carbon atoms, and R.sup.1 is R or aryl.

摘要:
The invention relates to zeolite particles which are at least partially coated with a coating that is capable of delaying the release of heat from the zeolite particles upon contact with water over time. The coating effectively at least partially blocks the pore structure of the zeolite particle from contact with water, thereby delaying contact between water and the zeolite, and prolonging the warming effect caused by such contact.
摘要:
An improved coating composition having one or more polymeric binders dispersed in a liquid medium, wherein the improvement comprises an anti-sag and anti-settling effective amount of oxidized ethylene-carbon monoxide copolymer having an acid number as determined by standardized titration of KOH of between about 4 and about 30 and a Brookfield viscosity at a temperature of 140.degree. C. of between about 50 and about 800 centipoises.
