Abstract: A process is described for preparing a functionalized EPM or EPDM artificial latex from the EPM or EPDM polymerization reactor without isolating the polymer. The process includes i) post polymerization functionalizing of an EPM or EPDM copolymer, ii) dispersing the functionalized copolymer in water with an appropriate surfactant and iii) removing the solvents. The resulting latex is useful in paper coatings, latex coatings, adhesives, and in impact modifiers.

Abstract: This invention relates to a method of sealing the porous surfaces that can be generated during the manufacturing and processing of molded plastic parts. Liquid thermoset coatings are applied to preheated parts and cured to create a barrier on the surface to gasses generated during heat curing of subsequently applied surface coatings. The liquid coating may be comprised of polyurethane forming components; those components in combination with unsaturated polyester resins; vinyl ester resin compositions; coatings derived from hydroxyl or carboxyl containing oligomers reacted with alkylated urea-formaldehyde, melamine-formaldehyde, and/or benzoquanamine-formaldehyde resins; and oligomers containing carboxyls reacted with triglycidyl isocyanurate.

Abstract: Coating compositions are disclosed which use a polyoxetane polymer having CH.sub.2 --O---CH.sub.2 --R.sub.f side chains where R.sub.f is a highly fluorinated alkyl or polyether. The coating compositions use polyisocyanates to create isocyanate terminated polymers from the poly(oxetanes) and from various polyols from alkylene oxides or polyester polyols. These can be reacted together to form block copolymer structures or can be linked together when the coating is crosslinked. A preferred method is to use blocked isocyanate groups. Another preferred embodiment is to use the composition as a abrasion resistant coating for glass run channels.

Abstract: A urethane coating composition is disclosed which uses fluorinated monohydric alcohols to increase abrasion resistance. One specific use of the coating is on vehicle sealing systems which use elastomeric substrates. The coating composition was found to have dramatically improved abrasion resistance in glass run channel applications over similar coatings without the fluorinated component.

Abstract: The present invention provides an emulsion polymerization synthetic isoprene-styrene/butadiene rubber for use in improved tire tread compositions is provided. The improved composition is a blend of a 1,4 cis-polyisoprene such as natural rubber and a synthetic rubber produced by emulsion polymerization which synthetic rubber includes isoprene and either styrene or butadiene or both styrene and butadiene. The tire tread composition has an excellent balance of good wear resistance and low rolling resistance as well as a low T.sub.g and good traction. These improved qualities for tire tread compositions have heretofore been unavailable in rubbers utilizing emulsion polymers, and have been achievable only with tire compositions including synthetic rubbers that are produced by solution polymerization.

Abstract: Liquid telechelic polymers are made from dienes and are produced via anionic polymerization. While having low molecular weight, for example less than 15,000, the telechelic polymers are generally gel-free, have high amounts of trans-1,4 structure, low vinyl unsaturation and low bulk viscosities. The liquid telechelic polymers are made utilizing a trimetallic initiator comprised of (1) an organopolylithium compound and (2) a complex of a trialiphatic substituted aluminum compound or derivative thereof and a barium salt of an organic alcohol.

Abstract: A composition useful as a catalyst in solution polymerization comprises (1) a barium, calcium and/or strontium alcoholate, (2) an organoaluminum compound and (3) an organomagnesium compound. (2) and (3) may be used as a complex with (1). The compositions can be used to polymerize ethylenically unsaturated monomers like butadiene, butadiene and styrene, and isoprene and heterocyclic monomers like oxiranes, thiiranes, siloxanes, thiatanes and lactams. The catalyst composition can produce polybutadienes and butadiene-styrene copolymers having a trans-1,4 content as high as 90%. The non-terminating features of the polymerization of this invention permit the preparation of functionally terminated butadiene based polymers and block polymers containing sufficient amounts of trans-1,4 butadiene units to crystallize.

Abstract: Divinyl benzene and/or diisopropenyl benzene in hydrocarbon solvent is added over a period of time at low temperature to a hydrocarbon solvent containing a C.sub.2-20 normal, secondary or tertiary alkyl or cycloalkyl lithium compound and a tertiary alkylamine having 2-4 carbon atoms prepared at low temperature to provide an initiator having an average of from 4 to 9 C-Li sites and a VPO Mn of from about 750 to 4,000. These initiators are useful in polymerizing dienes and vinyl monomers to provide star polymers having an average of from about 4 to 9 arms or branches. These star polymers among other things are useful low profile or low shrink additives for FRPs, e.g., glass fiber reinforced plastics.
