摘要： A surfactant for forming stable dispersions of rosin esters compatible with elastomeric latexes, the surfactant having the formula R1—R2—R3. R1 and R3 are each rosin (i.e., rosin, rosin dimer or a mixture of rosin and rosin dimer). R2 is selected from the group consisting of polyethylene glycol and polyethylene glycol-R4-polyethylene glycol wherein R4 is rosin (i.e., rosin, rosin dimer or a mixture of rosin and rosin dimer). The surfactant is prepared by esterifying the rosin material with polyethylene glycol.

摘要： Synthetic comb copolymers which elicit controlled cellular response, methods of applying these polymers to various surfaces, and methods of using the polymers for modifying biomaterial surfaces, in tissue engineering applications and as drug delivery devices are provided. The comb copolymers are comprised of hydrophobic polymer backbones and hydrophilic, non-cell binding side chains which can be end-capped with cell-signaling ligands that guide cellular response. By mixing non-cell binding combs with ligand-bearing combs, the surface concentration and spatial distribution of one or more types of ligands, including adhesion peptides and growth factors, can be tuned on a surface to achieve desired cellular response. In one embodiment, the combs are used as stabilizing agents for dispersion polymerization of latexes. The comb-stabilized latexes can be applied to substrates by standard coating operations to create a bioregulating surface, or used as drug delivery agents. In another embodiment, the combs can be blended in small quantities to a hydrophobic matrix polymer and processed to affect the surface segregation of the comb. The comb copolymers are formed in one embodiment by providing a biodegradable polyester backbone that includes reactive groups, and reacting the reactive groups in the backbone with reactive chain ends on a low molecular weight hydrophilic polymer. In another embodiment, non-biodegradable comb copolymers are formed by free radical synthesis of a hydrophobic monomer and a hydrophilic macromonomer. In all of the above embodiments, a portion of the hydrophilic polymer side chains can be covalently coupled to cell-signaling ligands such as adhesion peptides or growth factors to control cellular response.

摘要： A process for producing a vulcanizable rubber composition containing silica and carbon black, comprises the step of intimately mixing at a temperature of from 130° to 180° C. at least a first cross-linkable unsaturated chain polymer with a first carbon black-based reinforcing filler, so as to obtain a first rubber composition capable of allowing a subsequent effective dispersion of a second silica-based reinforcing filler and of a second cross-linkable unsaturated chain polymer. The rubber composition thus obtained shows a homogeneous dispersion of the reinforcing fillers, in particular of the silica-based reinforcing filler, constant physical-mechanical characteristics, and improved drawability, and is particularly suitable for the manufacture of tire treads with low rolling resistance.
