摘要:
A blend of styrene-isobutylene-styrene based thermoplastic elastomer and organoclay-filled polyamide is disclosed which has good processability and more effective barrier properties for oxygen than the blend using amorphous or crystalline polyamide without organoclay.

摘要:
A thermoplastic elastomer compound is disclosed having copolyester elastomer, epoxidized soybean oil, and vulcanized vegetable oil. The compound has a biorenewable content of at least about 50 weight percent of the compound. The compound can be used to make a plastic article needing a Shore A hardness of from about 40 to about 70. The compound is a sustainable solution for extruded or molded articles.

摘要:
A blend of any of three specific olefin polymers and ethylene/alpha-olefin interpolymer is disclosed. Optionally, the blend also includes styrene-isobutylene-styrene thermoplastic vulcanizate and calcium carbonate filler. The blend has good processability and passes Olive Oil Extraction Test EU82/711/EEC and the FDA Food Contact Test required at 21 CFR §177.2600, enabling plastic articles of the blend to be used as thermoplastic elastomers in food handling and storage articles.
摘要:
A blend of thermoplastic polyester elastomer, hydrogenated styrenic block copolymer, and high styrene content styrenic block copolymer is disclosed which has good processability and more effective abrasion resistance than the blend using polystyrene in place of the high styrene content styrenic block copolymer.

摘要:
This invention relates to a roofing or siding membrane comprising a non-woven mat coated with an asphaltic composition containing, in addition to 35-75 wt. % bitumen, a mixture of isotactic and amorphous propylene polymers and between about 0.08 and about 15 wt. % of a functionalized, olefin polymer to provide a non-staining membrane of high tensile strength, low polyolefin content with respect to asphalt, improved compatibility between asphalt and non-functionalized polymers and reduced light end asphalt and polymer exudates. The invention also relates to a method for preparing the membrane.
摘要:
Dynamic vulcanizates of an engineering thermoplastic ("plastic"), e.g. a polyamide or polyester, with acrylate rubbers having dissimilar functional groups are prepared with a metal fatty acid salt in the absence of a conventional curative, provided the rubbers are molecularly intermixed. An acrylate rubber with halogen functionality ("AcrRubHal") is thus crosslinked in a single mixing stage with an acrylate rubber having carboxyl, hydroxyl or epoxy functionality ("AcrRubX") in a "plastic". Quaternary ammonium salts and tertiary amines do not function as curatives, as one might expect. But a metal fatty acid salt, preferably a metal stearate or oleate and concentrates thereof effectively crosslink the rubbers. TPVs produced without conventional curing agents are relatively "soft", but have highly desirable low temperature physical properties and oil resistance.
