Process for preparing graftlinked heteropolymer film
TLDR
In this paper, the production of HETEROPOLYMER LATEX PARTICLES wherein the particles consist essentially of a first-stage RUBBERY CROSSLINKED EMULSION POLYMER HAVING A TG BELOW 10* C.Abstract:
PRODUCTION OF HETEROPOLYMER LATEX PARTICLES WHEREIN THE PARTICLES CONSIST ESSENTIALLY OF A FIRST-STAGE RUBBERY CROSSLINKED EMULSION POLYMER HAVING A TG BELOW 10* C. COMPRISING AT LEAST ONE C1 TO C8 ALKYL ACRYLATE AND A GRAFTLINKER AND A SECOND-STAGE THERMOPLASTIC POLYMER HAVING A TG ABOVE ABOUT 60* C. COMPRISING A HARD ALKYL ESTER OF METHACRYLIC ACID GRAFTLINKED TO SAID FIRST-STAGE BY ADDING GRADUALLY A STREAM OF SAID SECOND-STAGE MONOMER TO SAID FIRST-STAGE AND POLYMERIZING RAPIDLY THE SECOND-STAGE MONOMER. THE POLYMER PARTICLES ARE PREFERABLY ISOLATED, DRIED AND CONVERTED INTO FILM USING HEAT AND PRESSURE.read more

Modified latex polymer compositions
TL;DR: In this paper, modified aqueous dispersions of water-insoluble latex polymer prepared by swelling an initial WIL polymer, prepared by emulsion polymerization, with additional ethylenically unsaturated monomer, including at least one monomer with two or more sites of ethylenic unsaturation, and subsequently polymerizing the additional monomer within the swollen latex particles.

Heteropolymer acrylic latices and textiles treated therewith
TL;DR: In this article, low temperature properties of resin-treated textiles are improved by using as the resin an acrylic emulsion polymer wherein the latex particles have a core-shell structure.

Impact resistant methacrylic resin composition
TL;DR: A transparent heat-resistant methacrylic resin composition comprising 1 to 99% by weight of a copolymer (I) obtained by polymerizing a monomer mixture of 98 to 40% of methyl methacrylate and 1 to 30% of an N-substituted maleimide, was presented in this paper.

Multilayer coatings by plasma enhanced chemical vapor deposition
TL;DR: In this paper, the authors proposed a process for preparing a multiple layer coating on the surface of an organic polymeric substrate by means of atmospheric pressure plasma deposition, the steps of the process comprising depositing a layer (first layer) of a plasma polymerized, optically clear, highly adherent, organosilicon compound onto the surface by atmospheric pressure plating.
