    摘要: The present invention is directed to a copolymer that includes a first radically polymerizable low surface tension (meth)acrylate monomer and one or more other radically polymerizable ethylenically unsaturated monomers. The copolymer has a polydispersity index of less than 2.5. The present invention further includes a controlled radical polymerization method to make the above described low surface tension containing copolymers. The method includes the steps of adding a first radically polymerizable low surface tension (meth)acrylate monomer and one or more other radically polymerizable ethylenically unsaturated monomers to a solution containing a suitable atom transfer radical polymerization (ATRP) initiator.

    摘要: A composition that includes a non-gelled copolymer that contains residues having structural units (I): where n is an integer from 1 to 10,000; R1 is linear or branched C1 to C4 alkyl; R2 is selected from the group consisting of methyl, linear, cyclic or branched C2 to C20 alkyl, alkenyl, aryl, alkaryl and aralkyl, and R3 is a group resulting from a post polymerization reaction selected from transesterification, transamidification and hydrolysis with a compound selected from hydroxy functional compounds and amine functional compounds. The composition may contain co-reactive functional groups and may be a thermosetting composition. A substrate may be coated with the thermosetting composition singly or as part of a multi-layer composite coating that includes a base coat layer and a substantially pigment free top coat layer.

    摘要: A belt-fed machine gun (1) for firing a multiplicity of cartridges (6) encased in sleeves (7), which sleeves are linked to form a belt (8). The machine gun includes a plurality of substantially parallel barrels (2) mounted for circumrotation, a plurality of cradles (5) for supporting the cartridges encased in the sleeves, said cradles being mounted for circumrotation with said plurality of substantially parallel barrels (2) wherein a number of the plurality of cradles in an operative condition are aligned coaxially with corresponding barrels, a housing (9) and a breechblock (10). The housing and said cradles (5) in an operative condition engage sleeves (7) encasing cartridges (6) to form chambers with said breechblock, wherein the breechblock includes a guide (11) for engagement with a follower (15) on the cartridges (6) to urge cartridge and sleeve (7) into engagement with a barrel (2). The gun (1) further includes a firing mechanism for initiating a propellant charge (18) in one or more of the cartridges (6) supported by cradles (5) in the operative condition.
