The specification discloses a method and additive for increasing the surface activity of non-polar polymeric materials, and a non-polar polymeric material exhibiting increased surface activity. The invention employs an additive of the formula

Polyepichlorohydrin-based tri-block additive for surface modification of

The specification discloses an additive composition for use in preparing adhesive formulations, particularly hot melt adhesive formulations based on A-B-A block copolymers which exhibit increased upper service temperatures. The additive composition comprises a preblend of of an A-block compatible reinforcing resin having a number average molecular weight ranging from about 2,000 to about 10,000 Daltons and a polydispersity index of less than about 4.0 and a B-block compatible resin. The A-block compatible reinforcing resin/B-block resin preblend enables introduction of more A-block reinforcing resin into the composition thereby increasing the overall upper service temperature of the adhesive formulation.

Additive composition and method for increasing the upper service

The specification discloses elastomeric compositions and methods for making elastomeric compositions containing silica. The elastomeric composition comprises an elastomeric matrix containing from about 1 to about 40 wt. % silica and from about 0.1 to about 20 wt. % of an additive selected from the group consisting of rosin acid or fatty acid monoesters of glycerol and block copolymers having at least one A-block derived from the group consisting of rosin acids and fatty acids and a B-block having a number average molecular weight in the range of from about 200 to about 2500 daltons derived from the group consisting of a polyethylene glycol (PEG) and a polyepichlorohydrin (PECH) polyol. The additive provides substantial improvement in the dispersion and adhesion of silica in the elastomeric matrix which substantially improves the strength and other properties of the material.
