Abstract: Blend compositions include at least one polydiorganosiloxane polyoxamide copolymer, and at least 70% by weight of at least one silicone tackifying resin. The blend composition is non-tacky at room temperature up to a temperature of at least 100° C. The polydiorganosiloxane polyoxamide copolymer can be a linear or branched copolymer. The blend compositions provide solid, non-powdery, and non-tacky delivery vehicles for silicone tackifying resin.

Abstract: 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.

Abstract: Branched polydiorganosiloxane polyamide, block copolymers and methods of making the copolymers are provided. The method of making the copolymers involves reacting one or more amine compounds including at least one polyamine with a precursor having at least one polydiorganosiloxane segment and at least two ester groups.
