    Abstract: This thermoplastic elastomer is present in a substantially solid state suitable for use as a binder for a propellant, explosive, and/or gas generant of a supplemental restraint system. The thermoplastic elastomer is formed from a composition including A blocks which are crystalline at temperatures below about 75° C. and B blocks which are amorphous at temperatures above about ?20° C. The A blocks are derived from oxetane derivatives and the B blocks are derived from oxiranes and derivatives thereof. The A blocks and B blocks are end-capped with a diisocyanate having a first isocyanate moiety that is substantially more reactive with the terminal groups of the blocks than the second isocyanate moiety, whereby the more reactive first isocyanate moiety is capable of reacting with the terminal groups of the blocks, leaving the less reactive second isocyanate moiety free and unreacted.

  • Patent number: 7378464
    Abstract: There is provided a heavy duty tire made by using as a tread rubber a rubber composition obtained by compounding 100 parts by mass of a rubber component consisting of 90-30% by mass of (a) natural rubber and 10-70% by mass of (b) a solution-polymerized styrene-butadiene copolymer rubber containing tin in at least one of a middle of a polymer molecular chain and a terminal of the molecular chain and having a bound styrene content of 28-45% by mass and a vinyl bond content in a butadiene portion of less than 30 mol % with 40-60 parts by mass in total of (c) carbon black and (d) silica, provided that an amount of (d) silica as a filler is 5-20 parts by mass. In the heavy duty tire, the resistance to uneven wear is considerably improved without damaging the heat buildup and wear resistance.

  • Patent number: 7244812
    Abstract: The invention relates to a method for reducing the amount of residual monomers in aqueous polymer dispersions means of chemical post-treatment. Post-treatment in the aqueous polymer dispersion is carried out by adding a redox system which contains a) 0.005-5 wt. % of an oxidation agent which contains an organic peroxide. and b) 0.005-5 wt. % of a reduction agent which contains sulfinic acids or salts thereof. Additionally the redox system can, optionally, contain catalytic amounts of a polyvalent metallic ion which can be treated in several valent stages. Post-treatment can be carried out at a temperature ranging from 20-100.degree. C. and at a PH-value ranging from 2-9. The invention also relates to the use of the inventive post-treated polymer dispersion for producing adhesives, coatings, powders, constructive chemical products or for refining textiles or paper.
