  • Patent number: 9180647
    Abstract: An interlayer comprised of a high flow, low molecular weight thermoplastic resin, and at least one plasticizer is disclosed. The use of a high flow, low molecular weight thermoplastic resin, and a plasticizer creates synergy allowing the flow of the interlayer to be increased without sacrificing other characteristics typically associated with an increased flow (e.g., increased blocking, decreased mechanical strength, and decreased manufacturing capability). In this regard, the high flow, low molecular weight thermoplastic resin provides a flow improvement, resulting in a high flow interlayer. As a result, a thinner interlayer can be utilized in forming multiple layer panels because the resulting thinner interlayer has improved flow properties.

  • Publication number: 20100249296
    Abstract: It is an object of the present invention to provide: a rubber stopper composition that is easy to mold and process, excellent in sealing properties and gas-barrier properties, low in propensity to elute into the contents, and satisfactory in needle penetration; and a medical rubber stopper made by using the same. The object of the present invention is attained by a composition made up in a predetermined way by dynamically cross-linking an isobutylene-based polymer in the presence of polyolefin with use of a hydrosilyl-group-containing compound and by further adding a softener to the isobutylene-based polymer thus cross-linked, the isobutylene-based polymer having an alkenyl group at a terminal thereof. To the composition of the present invention, a block copolymer consisting of a polymer block (a) composed mainly of an aromatic vinyl-based compound and a polymer block (b) composed mainly of isobutylene or a lubricant can be added.

  • Publication number: 20100152341
    Abstract: Compacted additive blends, or polymer stabilization agent blends, can be added during the post-polymerization process to enhance the processability performance of polymers. The addition of certain compaction aids, such as high melting or non-melting metallic silicates and others, increases the resistance to friability of the compacted additive pellets. These compaction aids are non-migratory during the compaction process and after introduction into the polymer resin and thus have no deleterious effects. The additive blend can contain a variety of suitable additives in addition to the compaction aids.
