Block copolymers having a molecular weight distribution of between 1. 0 and 5. 0 comprising at least one block of polymerized alkyl methacrylate monomer(s), wherein from 50 to 100% by weight of the monomers for forming the alkyl methacrylate block are C12-C30 alkyl methacrylates, and a block of a polymerized conjugated alkadiene. The block copolymers of the present invention are useful as viscosity index improvers in lubricating oil compositions as well as compatibilizers for compositions containing both polymethacrylates and olefin copolymers or hydrogenated block polymers.

A lubricant composition comprising a major amount of baseoil lubricant and a minor amount of lubricant additive. The lubricant additive includes (a) a dispersant containing at least one member selected from hydrocarbyl-substituted succinimides, hydrocarbyl-substituted amines, and Mannich base adducts derived from hydrocarbyl-substituted phenols condensed with an aldehyde and an amine, and (b) a viscosity index improver that includes a substantially linear block copolymer having a number average molecular weight as determined by gel permeation chromatography ranging from about 50,000 to about 250,000. The block copolymer is derived from a conjugated diene monomer containing no less than 5 carbon atoms and a monoalkenylarene monomer, wherein the block copolymer has an aromatic content ranging from about 10 wt. % to about 50 wt. % and an olefinic unsaturation ranging from about 0. 5 wt.

Fibrous material suitable for incorporation into filter elements of smoking articles such as cigarettes are impregnated with additives and agents such as flavorants, flavorant-enhancers and/or free radical scavengers. The fibrous material is contacted with the additive dispersed in a high pressure gas or supercritical fluid (SCF) held at elevated pressures. The high pressure gas or SCF swells the fibrous matrix and enables the additive to be incorporated within the matrix. When pressure is reduced, the gas or SCF vaporizes and leaves the additive embedded in the fiber interstices. As a result, the additive is slowly released over a finite period of time. When incorporated into a cigarette filter, the additive is released at a desired rate from the interior of the fibrous filter into the cigarette smoke.

Delivery of additives in a smoking article is provided through thermally degradable, robust immobilized additive inserts. Additives can be immobilized in an elongated device or an insert, wherein the elongated device or the insert is sufficiently robust to allow the elongated device or the insert to be manually or machine inserted into a smoking article while maintaining the structure of the elongated device or the insert. By providing additives in the form of thermally degradable immobilized additive inserts, migration and/or loss of the additives in a smoking article prior to smoking can be reduced.
