First articles with covalently attached thiocarbonylthio-containing groups are provided. More specifically, the first articles are a functionalized substrate that contains a solid polymeric substrate with a plurality of thiocarbonylthio-containing groups covalently attached directly to carbon atoms in a polymeric backbone of the solid polymeric substrate. Methods of making the first articles with covalently attached thiocarbonylthio-containing groups are provided. Additionally, second articles and methods of using the first articles to generate second articles with covalently attached polymeric chains are provided.

A method of making a buff-coated article includes disposing a tie layer on at least a portion of a major surface of a substrate and buff-coating a powder onto at least a portion of the tie layer. Buff-coated articles are also disclosed.

Methods of (co)polymerizing ethylenically-unsaturated materials, including the steps of providing a non-deaerated mixture of free radically (co)polymerizable ethylenically-unsaturated material in a batch reactor, exposing the non-deaerated mixture to a source of ionizing radiation for a time sufficient to initiate (co)polymerization of at least a portion of the free radically (co)polymerizable ethylenically-unsaturated material, and allowing the free radically (co)polymerizable ethylenically-unsaturated material to (co)polymerize under essentially adiabatic conditions while continuing to expose the mixture to the source of ionizing radiation for a time sufficient to yield an at least partially (co)polymerized (co)polymer. The ethylenically-unsaturated materials are selected from vinyl-functional monomers, vinyl-functional oligomers, vinyl-functional macromers, and combinations thereof. The mixture is preferably free of thermally-induced or UV-induced free radical polymerization initiators. The source of ionizing radiation may be a gamma ray source, an x ray source, an electron beam source with an emission energy greater than 300 keV, and combinations thereof.

Methods of forming an adhesive composition including the steps of (a) combining a non-deaerated mixture comprising at least one free radically (co)polymerizable ethylenically-unsaturated material with a sealable packaging, wherein the packaging contains the non-deaerated mixture; (b) sealing the non-deaerated mixture in the packaging to form a sealed packaging; and (c) exposing the non-deaerated mixture in the sealed packaging to a source of ionizing radiation for a time sufficient to initiate (co)polymerization of at least a portion of the at least one free radically (co)polymerizable ethylenically-unsaturated material to form an adhesive composition in the sealed packaging. The (co)polymerization takes place essentially non-adiabatically. At least a portion of the packaging is meltable and mixable with the adhesive composition so as to provide a flowable coatable adhesive composition when the sealed packaging containing the adhesive composition is heated to a temperature sufficient to melt at least a portion of the packaging.

A delivery system for delivering a horticultural agent to a plant including a carrier adapted to be placed in proximity to a root system of a plant, the carrier being of a material which is biodegradable and dissolvable upon prolonged exposure to water, and the horticultural agent being adhered to or admixed with the carrier and being dissolvable upon prolonged exposure to water.
