Abstract: Disclosed is a method and apparatus for the playing of a mediated war game by two or more players, called "Mitcrons", and a Mediator using a game apparatus which comprises at least two game pieces per player, called "Bots", and at least three transparent sheets having identical geographical maps permanently affixed thereon which are from time to time superimposed over each other so that the Mediator can record (1) each Mitcron's ordering of its Bot' moves toward a predetermined goal and blasts to destroy enemy Bots; and (2) spotting by each Mitcron of the other Mitcron's Bots.

Abstract: Melt preparation of polyarylate with catalyst system comprising an imidazole.

Abstract: A process for polymerizing .epsilon.-caprolactam to form a nylon-6 block copolymer in which a reactant stream containing .epsilon.-caprolactam, and a lactam polymerization initiator is brought into polymerizing admixture with a reactant stream containing .epsilon.-caprolactam and a lactam magnesium halide, wherein sufficient 2-oxo-1-pyrrolidinyl compound is added to the admixture either as 2-pyrrolidinone, 2-oxo-pyrrolidinyl magnesium halide or 2-oxo-1-pyrrolidinyl capped initiator compound to enhance the rate of polymerization of the .epsilon.-caprolactam. The lactam polymerization initiator is a telechelic oligomer or polymer containing a backbone which provides elastomeric segments in the nylon-6 block copolymer, and attached to the backbone are activated initiator groups which initiate the polymerization of .epsilon.-caprolactam in the presence of the lactam magnesium halide.

Abstract: Compositions for the preparation of block copolylactams comprising lactam, lactam polymerization initiator and an effective amount of a viscosity enhancing compound selected from the group consisting of the lactamates and .omega.-amino acid salts of barium, calcium and strontium.

Abstract: A composition containing acid halide functional materials, which are useful in the preparation of nylon block polymers, selected from the group consisting of: ##STR1## wherein, X is a halogen;a is an integer equal to 1, 2 or 3;b is an integer equal to 2 or more;R is a di- or a poly-valent group selected from hydrocarbon groups and hydrocarbon groups containing ether linkages;Z is a segment of: (1) a polyether; (2) a polyester containing polyether polyester hydrocarbon segments, (3) a hydrocarbon; (4) a polysiloxane; or (5) combinations thereof.

Abstract: A process for coating a substrate with a film of cured polymer in which a mixture of a poly (.alpha., .beta.-ethylenically unsaturated) oligomer, a polyallyloxy activator compound containing an effective amount of a free radical polymerization initiator and a catalytic amount of metal drier is prepared, the admixture is applied to the substrate in an air or oxygen rich atmosphere and the coated substrate is then placed in an atmosphere substantially free of oxygen until the coating has cured to a substantially tack-free condition.

Abstract: A new miniature rose variety having uniquely colored semi-double flowers wherein the bottom two-thirds of the petal is white and the top one-third is light red.
