Splash guarded elevating bathing tub

Walk around elevating tub

An elevating animal bathing tub having an elevating platform and a tub formed of light weight strong material secured to the platform. The tub is provided with a downward directed skirt and the elevating platform is provided with an upward directed skirt that telescopes with the skirt on the tub to shield the elevating apparatus. The tub is provided with an entry cutout so that when the tub is in the lowered position an animal to be bathed can easily enter the tub. The tub is configured to accept utilities and attachments specific to the tasks to which the tub is to serve.

A super-toughened multiphase thermoplastic composition is provided by combining at least one modified selectively hydrogenated conjugated diene/alkenyl arene block copolymer to which has been grafted an effective amount of succinic groups primarily in the selectively hydrogenated conjugated diene blocks thereof and optionally at least one unmodified selectively hydrogenated conjugated diene/alkenyl arene block copolymer with at least one .alpha.,.omega.-polyamide.

High impact resistant blends of thermoplastic polyamides and modified

The present invention relates to a thermally stable modified selectively hydrogenated high 1,2 content block copolymer wherein a functional group is grafted to the block copolymer in the vinylarene block.

Modified block copolymers functionalized in the monoalkenyl aromatic or

The present invention relates to a high impact resistant polymeric composition comprising a polyester and a thermally stable modified selectively hydrogenated block copolymer wherein at least one acid compound or a derivative thereof is grafted to the block copolymer. Poly(alkylene terephthalates) are preferred thermoplastic polyesters. The block copolymer will comprise at least one polymeric block of a monoalkenyl arene and at least one polymeric block of at least one conjugated diolefin.

High impact resistanct blends of thermoplastic polyesters and modified

Blends of (a) a linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon with (b) a partial non-alkali metal salt of a polymer of an .alpha.-olefin, an unsaturated carboxylic acid, and optionally a third monomer, exhibit improved properties of processability and toughness.

Blends of linear alternating polyketones and partially neutralized

Blends of (a) a linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon and (b) a maleated polyolefin polymer exhibit improved properties of thermal stability, impact resistance as better processability.

Polymer blend

The present invention relates to an impact resistant polymeric composition, useful as a structural material, comprising a polyamide such as a nylon 6,6, a polyolefin such as polypropylene, and a functionalized elastomer such as a maleated-EPDM.

Impact resistant blends of thermoplastic polyamides, polyolefins and

A process for solvent welding pure polybutene-1, or blends or copolymer of polytbutene-1 to polybutene-1 where the polybutene-1 items are contacted with a solvent such as methylene chloride, tetrahydrofuran or cyclohexane and then contacted together within a variable period of time after solidification of the polybutene-1 items.

Solvent welding polybutene-1

Polymer blends of improved properties are produced by uniformly mixing a linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon, and a copolymer of a vinyl aromatic monomer and an alkenyl nitrile.

A toughened multiphase thermoplastic composition is provided by incorporating at least one functionalized, selectively hydrogenated alkenyl arene/conjugated diene block copolymer to which has been grafted an effective amount of carboxyl functional groups primarily in the alkenyl arene blocks thereof with a thermoplastic polyester. The carboxyl functional groups may be in the form of carboxylic acids, their salts, their esters, and combinations of two or more of these.
