Dip molding composition, method of producing glove, and glove
Provided is, a glove production method including: (1) the step of immersing a glove forming mold in a liquid coagulant containing calcium ions so as to allow the coagulant to adhere to the glove forming mold; (2) the dispersion step of leaving a dip molding composition to stand with stirring; (3) the dipping step; (4) the gelling step; (5) the leaching step; (6) the beading step; (7) the precuring step; and (8) the curing step, in which method the steps (3) to (8) are performed in the order mentioned, and the dip molding composition has a specific formulation.
Acrylic composition having an increased resistance to alcohols, oils and fats
A transparent acrylic-based polymer composition has an increased resistance to alcohols, oils and fats. The polymer composition contains: (A) a copolymer of alkyl(meth)acrylates, aromatic vinyl monomer and unsaturated carboxylic acid anhydride; (B) a copolymer containing aromatic vinyl monomer and a vinyl cyanide monomer; and (C) a particulate core-shell type graft copolymer containing a butadiene-based core as a rubbery phase and a copolymer containing alkyl(meth)acrylates and, optionally, aromatic vinyl monomer as a hard phase. The components A and B form a polymer matrix and the particulate core-shell type graft copolymer C is dispersed in said polymer matrix.
Carbonization shape forming of oxidized PAN fiber preform
A single stage OPF-to-carbon preform shape forming method includes positioning an oxidized PAN fiber preform with a female forming tool, positioning a vacuum bag over the oxidized PAN fiber preform, and vacuum forming the oxidized PAN fiber preform into a shaped body. The vacuum formed shaped body (while still in the shape forming fixture) may be loaded into a carbonization furnace and carbonized. The vacuum bag may be burned away in the carbonization furnace during carbonization.
