US Classification:

428 357, 427489, 428336

Abstract:

A process for preparing an adherent coating on an object (as well as the coated object) by first plasma polymerizing a first organosilicon compound under conditions to deposit a polyorganosiloxane layer onto the object; and/or then plasma polymerizing a second organosilicon compound under conditions to deposit a silicon oxide layer on the polyorganosiloxane layer or directly on the object, the object comprising a polymer composition comprising (i) from 99 to 50 weight percent of a polymer having more than 90 weight percent monomer units containing three carbons and optionally monomer units selected from the group consisting of alpha olefins containing two carbons and/or from four to twelve carbons, and (ii) from 1 to 50 weight percent of a second copolymer comprising monomer units selected from the group consisting of alpha olefins containing two carbons and alpha olefins containing from four to twelve carbons and optionally up to 10 weight percent of a diene monomer containing less than thirteen carbons; or the object comprises an alternative polymer composition comprising (iii) from 1 to 50 weight percent of a copolymer of propylene and up to 10 weight percent of a comonomer selected from the group consisting of alpha olefins containing two carbons and/or from four to twelve carbons, and (iv) from 99 to 50 weight percent of an impact copolymer consisting of a blend of homopolymer polypropylene with up to 50 weight percent of a random copolymer of propylene and an alpha olefin containing two carbons and/or from four to twelve carbons.

International Classification:

B32B 5/32
B32B 27/32

US Classification:

428218, 428220, 4284231, 428523

Abstract:

Structural insulation sheathing (SIS), preferably in the form of a panel, comprises a structural facer and an insulation member. The structural facer and insulation members are in intimate, planar contact with one another, both are plastic, and the SIS structure meets both the structural (i.e., ASTM E72) and insulation (R>2) requirements for the North American residential market. The structural facer member of the SIS structure is high-density polyolefin foam. The structural facer comprises a skin/core structure with the skins of a higher density than the core, and the structural facer has a flexural modulus typically of at least about 30,000 pounds per square inch (psi). The insulation member of the SIS is a foamed sheet of thermoplastic, e.g., polyisocyanurate.

US Classification:

428141, 427489, 264129

Abstract:

A process for improving the barrier performance of a plasma coated object comprising a polyolefin is disclosed. The process involves ensuring that the surface of the object to be coated is smooth as characterized by having a root-mean-square surface roughness that varies by less than the thickness of the coating to be applied, typically less than 100 nm. The invention also relates to a process for improving the stain resistance of polyolefin based articles comprising plasma polymerizing an organosilicon compound under conditions to deposit a polyorganosiloxane layer onto the article and/or (b) plasma polymerizing a organosilicon compound under conditions to deposit a silicon oxide layer directly on the article or onto a polyorganosiloxane layer prepared according to step (a).
