US Classification:

428 366, 428 357, 428 367, 428 365, 428 369, 428 3691, 428 3692, 526343, 5263171, 264464

Abstract:

The invention includes a copolymer of vinylidene chloride with at least one monounsaturated comonomer and at least one branching monomer in an amount sufficient to increase molecular weight over that of a polymer prepared using the same process and same monomers in the same relative amounts except without the branching monomer, but preferably the branching monomer is present in a quantity not sufficient to result in measurable crosslinking as determined by solubility in tetrahydrofuran at up to 83 C. The invention includes a process for making the polymer and processes for forming the copolymer or compositions thereof as well as articles comprising the copolymer and compositions thereof. The copolymer exhibits improved bubble stability and is particularly useful for processes in which the copolymer is at least partially oriented in formation such as blow molding, formation of monofilament fiber and film blowing.

International Classification:

C08K 5/1515
B28B 3/20

US Classification:

524114, 2641761

Abstract:

The present invention includes a monofilament obtainable by extruding a composition comprising: (a) at least one vinylidene chloride polymer/methyl acrylate interpolymer having at most about 6 weight percent methyl acrylate mer units in the polymer; and (b) at least about three weight percent total plasticizer, of which about 0. 5 weight percent based on total composition weight is an epoxy plasticizer or combination thereof through a die such that monofilament is formed. Optionally, and preferably in extruders wherein the composition of (a) and (b) exhibits less uniformity in extrusion than is desired, at least one methacrylic polymer is also added. The invention also includes a process of extruding a composition of at least (a) and (b) to form a monofilament.

Abstract:

Highly desirable organic liquid soluble multifunctional lithium containing initiators are prepared by reacting on organo lithium compound with an organic compound containing at least one group of the configuration 1,3-bis(1-phenylethenyl)benzene. Such initiators can be prepared in the absence of polar solvents and are very desirable for the polymerization of dienes such as butadiene to a desirable 1,4 configuration.

Abstract:

Highly desirable multifunctional lithium containing initiators are prepared by reacting a compound such as an organo lithium with an organic compound containing at least two 1,1-diphenylethylene groups. Such initiators can be prepared in the absence of polar solvents and are very desirable for the polymerization of dienes such as butadiene to a desirable 1,4 configuration. Several di-lithium compounds have been employed to initiate polymerization of various unsaturated organic monomers.
