A photosensitive elastomeric composition which comprises a high molecular weight elastomeric diene polymer having a number average molecular weight (Mn) of about 30,000 to 125,000, and a Mooney viscosity (ML-4 at 100.degree. C.) of 35 or higher; a low molecular weight diene polymer having a number average molecular weight of about 1,000 to 25,000; a photopolymerizable, ethylenically unsaturated cross-linking agent; and an addition polymerization initiator activatable by actinic radiation.

Photosensitive elastomeric composition for flexographic printing plates

A photopolymer elastomeric article designed to be used primarily in a flexographic printing system comprising: a polymer matrix made up of a mixture of syndiotactic 1,2-polybutadiene and cis-1,4-polyisoprene; a photoinitiator, which is a compound, which when irradiated, will initiate polymerization and/or crosslinking; and optionally, 0-3 phr of photopolymerizable, ethylenically unsaturated crosslinking agent, as typified by esters of acrylic or methacrylic acid.

Syndiotactic polybutadiene composition for a photosensitive printing

An elastomeric article suitable for flexographic printing comprising an elastomeric natural or synthetic dienoid polymer or copolymer, a photopolymerizable, ethylenically unsaturated crosslinking agent and a photoinitiator, portions of said article having been exposed to a photopolymerizable-effective amount of actinic radiation through an image bearing transparency having clear and opaque areas, and processed to remove the soluble portion of said plate situated beneath the opaque areas of the transparency during exposure, and said processed plate having been treated with iodine so as to render its printing surface tack-free and resistant to hardening when further exposed to actinic radiation.

Iodine treated elastomeric article

A photopolymer elastomeric article designed to be used primarily in a flexographic printing system comprising three constituents: a chlorosulfonated polyethylene polymer matrix, a photopolymerizable, ethylenically unsaturated crosslinking agent, as typified by esters of acrylic or methacrylic acid and a photoinitiator, which is a compound, which when irradiated, will initiate polymerization and/or crosslinking.

A pneumatic tire of the tubeless type, embodying a layer of puncture sealant composition based on:

Puncture sealing composition and tire

A pneumatic tire of the tubeless type, embodying a layer of puncture sealant composition based on a major proportion of low molecular weight liquid elastomer with a minor proportion of a high molecular weight elastomer, containing a crosslinking agent in an amount sufficient to give a partial cure. An example of the composition of the invention is a blend of 60 parts of depolymerized natural rubber and 40 parts of cis-polyisoprene, partially crosslinked by the action of 6 parts of tetra-n-butyl titanate so as to provide a gel content of about 40%.

A composition comprising thermoplastic copolymers of styrene or substituted styrene with acrylonitrile or substituted acrylonitriles or acrylonitrile-butadiene-styrene polymers in admixture with a combination of a discontinuous glass fiber and a particulate filler.
