Abstract: The disclosure relates to an adhesive composition comprising a partially hydrogenated styrenic block copolymer (p-HSBC) and an amorphous polyolefin (APO) having a density of less than 1 g/cm3 and a softening point of 10-120° C. The composition has desirable elastomeric properties as well as beneficial processability characteristics. The unique combination of processability and performance attributes results in the adhesive compositions useful in a variety of applications such as disposable nonwoven hygienic articles, paper converting, flexible packaging, woodworking, carton, case sealing, and other assembly applications.

Abstract: The invention relates to a process for preventing or restricting oil spills from oil tankers. The process comprises application of block copolymer particles having a high active surface in the form of fine particles or a fluffy structure. The block copolymer has at least one predominantly poly(vinyl aromatic compound) block and at least one predominantly poly(conjugated diene) block. The process may comprise introduction of the block copolymer into damaged compartments of the ship and permanent placement of the block copolymer in the double hull space of the ship. The process may further comprise automatic introduction of the block copolymer upon detection of a hard shock or high temperatures.

Abstract: A foam and pre-foam production process, and a foam and a pre-foam is described. The process comprises the steps of: forming a pre-foam composition comprising oil(s), thermoplastic elastomer(s) and heat expandable thermoplastic particles encapsulating heat expandable gas or liquified gas, the said particles being present in an amount which provides the required foam cell density. A heat treating step for the said composition to cause the particles to expand and produce a foam from the said composition is also described.

Abstract: The present invention provides a thermofusible elastomer composition comprising:(a) 100 phr of a selectively hydrogenated block copolymer component comprising an A'B' block copolymer and a multiblock copolymer having at least two end blocks A and at least one mid block B wherein the A' and A blocks are monoalkenyl arene polymer blocks and the B' and B blocks are substantially completely hydrogenated conjugated diene polymer blocks, the number average molecular weight of the A' and A blocks are between about 3,000 and about 7,000 and the monoalkenyl arene content of the multiblock copolymer is between about 7% and about 22% by weight;(b) 20 to 50 phr of at least one high melt flow polyolefin;(c) 0 to 19 phr of a plasticizing oil selected from naphthenic oils and paraffinic oils; and(d) 0 to 40 phr of at least one poly(conjugated diene) block compatible resin wherein the elastomer composition has a particle size of 1400 .mu.m or less.This composition is used in low shear processes.

Abstract: The present invention is a free flowing powder composition which contains an elastomeric block copolymer and significant amounts of a plasticizing oil. The powder forms a homogeneous layer and is suitably applied as a carpet backing.

Abstract: Block copolymer containing compositions, to be used in rotational molding, the compositions comprising at least:(a) 100 parts by weight of a block copolymer containing at least two predominantly poly(monovinyl aromatic) blocks and at least one predominantly poly(conjugated diene) block, the poly(conjugated diene) block preferably being selectively hydrogenated;(b) from 10 to 80 parts by weight and preferably from 20 to 50 parts by weights, of a linear low density poly(ethylene) or copolymers of predominantly ethylene and minor amounts of other .alpha.-olefin comonomers; and(c) from 20 to 100 parts by weight and preferably from 20 to 45 parts by weight of a plasticizer.

Abstract: Conveyor belt, obtainable by application of a block copolymer composition, comprising at least an optionally modified block copolymer, containing at least two terminal poly(vinylaromatic) blocks and at least one internal poly(conjugated diene) block, a non-aromatic plasticizing oil, and a terminal block compatible resin on at least one side of a fabric having from 5 to 25 threads per cm and process for the manufacture of it, while the threads in said fabric have a thickness in the range of from 2.mu. to 300.mu..
