    • A two-step process for production of thermoplastic elastomer, which comprises dynamically vulcanizing polypropylene and olefinic rubber in the presence of peroxide (1st step), and dynamically vulcanizing the vulcanized mixture, polypropylene and halogenated butyl rubber in the presence of zinc oxide (2nd step). In another method (a) polyolefin and olefin rubber are dynamically cross-linked in the presence of an organic peroxide and (b) in a separate second operation a dynamically vulcanized blend comprising polyolefin and halogenated butyl rubber is prepared and mixed with (a) to disperse (a) and (b) in one another. The thermoplastic elastomer composition is useful in materials for parts of automobiles.In an example, pp 9 wt. % parts, EPDM 21 wt. % parts, peroxide 0.3 wt. % part and divinylbenzene 0.5 wt. % part were blended and supplied to the first hopper (1) of biaxial extruder as shown in a figure. In the first blending zone (2), temperature and residence time are 200.degree. C. and 60 seconds respectively. And then, to the second hopper (3) of the extruder, pp 50 parts and the vulcanized product (EPDM+chlorinated butyl rubber) 20 parts were supplied and extruded in the heat blending zone (4) above mentioned mixture for 30 seconds of residence time. The physical properties of the composition are MFR: 18, Flex. Mod.: 3,300 (23.degree. C.) and 1,150 (80.degree. C.), Tens. at break: 105, Elong.: 420%, Izod.: No break (room temperature) and 25 (-40.degree. C.) Shore-D: 58, Flow marks: good and paintability: 100/100.

    • A method of producing compounds in which the rubber phase contains a polyolefin and a halobutyl rubber, which is partially crosslinked, to which composition is then added additional polyolefin and a vulcanizable olefinic rubber, which is then further crosslinked using organic peroxides, and then blended with a styrenic rubber. The TPE compounds incorporate (A) polypropylene 10-90 weight parts (wt. pts.), (B) halobutyl rubber 90-10 wt. pts. (where (A)+(B)=100), (C) an olefinic rubber 10-120 wt. pts., (D) mineral oil softener 5-120 wt. pts., which are then treated thermally in the presence of (E) MOx and/or MCl, to which composition of 100 weight parts is added (F) polyolefin 100-600 wt. pts., and (G) a vulcanizable olefinic rubber 50-500 wt. pts. The resulting blend is then thermally treated with (H) organic peroxide(s), to which blend of 100 wt. pts. is then added and uniformly dispersed (I) 5-150 wt. pts. of styrenic rubber.The method produces thermoplastic elastomer compositions which can be molded into large parts with smooth surfaces that accept paint well, have a good balance of flexibility and strength.
