摘要:
A chlorosulfonated or chlorinated polyethylene dispersed in a polyolefin, vulcanized and then the vulcanizate dispersed into a thermoplastic chlorosulfonated or chlorinated polyethylene forming a partially crosslinked thermoplastic chlorosulfonated or chlorinated polyethylene vulcanizate having good interply adhesion, hot weld strength, commercial processability, and crack resistance.
摘要:
The invention is a multilayer tire sidewall having an outer layer prepared from a blend of isomonoolefin/para-alkylstyrene copolymer and general purpose rubbers. The inner layer comprises general purpose rubber. The resulting sidewall exhibit good ozone resistance and fatigue crack resistance as well as a reduction in staining and discloration.

摘要:
An adhesive composition containing a linear polyester polyurethane, a halogenated polyolefin, an epoxy/silane adduct, a Diels-Alder adduct of a halogenated cyclic conjugated diene and a block copolymer of styrene and butadiene and a crosslinking compound for the linear polyester polyurethane. The adhesive composition is preferably utilized as a two-component adhesive for bonding vinyl polymers such as polyvinyl chloride to various substrates such as glass. The adhesive composition exhibits substantial resistance to environmental conditions without the requirements of a pre-heating step.
摘要:
Low molecular weight olefin resins are blended with small amounts of high molecular weight olefin resins and the blends are chlorinated or chlorosulfonated. Melt and film strengths of the resultant low molecular weight chlorinated and chlorosulfonated resins are thereby increased sufficiently to enable recovery by means of methods which require film or strand formation. The chemical properties and solution characteristics of the blends are substantially maintained compared to those of the low molecular weight chlorinated resins themselves.
摘要:
A curable, processable, substantially lead-free composition for moisture resistant cable jacket applications based on chlorinated polymeric materials stabilized by an epoxy compound.
摘要:
Novel, uncured tapes are provided comprising a raw polymer mixture of HDPE, LLDPE or isotactic polypropylene, chlorosulfonated polyethylene rubber, a small amount of a filler or pigment and, optionally, a minor proportion of chlorinated polyethylene rubber or an elastomeric polymer. They are self-bonding when elongated at least about 50% and wrapped on a substrate, and possess various degrees of flame resistance depending on their composition.
摘要:
The invention provides a film composition comprising a thermoplastic polymer having a melt flow rate of 20 to 2000 (g/10 min), and a flame-retardant, and a self-extinguishing laminated film comprising at least two thermoplastic polymer films, at least one of the thermoplastic polymer films being a meltable film prepared from the composition.
摘要:
Chlorinated ethylene-.alpha.-olefin copolymer rubber of the present invention is characterized in that the content of chlorine bonded to primary carbon atom is 0.6% by weight or more and the content of chlorine bonded to tertiary carbon atom is 1.6% by weight or less. This chlorinated ethylene-.alpha.-olefin copolymer rubber has a high vulcanization speed and excels in heat resistance. Additionally, this thermoplastic elastomer composition consisting of this vulcanizate and crystalline polyolefin resin particularly excels in moldability and processibility.
