Abstract

New saturated, long chain, linear primary alcohols are disclosed. Previously available up to molecular weight values (Mn) of approximately 700 daltons, the new products extend the range to approximately 2000 daltons. The new products are produced via controlled polymerization to yield products with consistent alcohol functionality of about 80% through the entire molecular weight range with a relatively narrow polydispersity of approximately 1.10. The products have a low viscosity while molten, and form highly crystalline, hard solid particles. The products can be micronized to particles as small as six microns.

Long Chain Primary Alcohols for Plastics Applications

New saturated, long chain, linear primary alcohols are disclosed.  Previously available up to molecular weight values (Mn) of approximately 700 daltons, the new products extend the range to approximately 2000 daltons.  The new products are produced via controlled polymerization to yield products with consistent alcohol functionality of about 80% through the entire molecular weight range with a relatively narrow polydispersity of approximately 1.10.  The products have a low viscosity while molten, and form highly crystalline, hard solid particles.  The products can be micronized to particles as small as six microns.

The new products have the following application benefits:

·         As antiblock additives for polymer resins.  The new primary alcohols can be used as internal and / or external antiblock agents for plastic resins.  As internal antiblock agents, the properties of the new primary alcohols allow consistent migration to the surface and helps minimize blocking tendencies during storage or use. As external antiblock agents, the new primary alcohols can be dispersed in solvent or water and applied to the surface of the polymer resin, or can be micronized to small particles and applied directly to the surface of the polymer resin.  The new primary alcohols can be used at levels up to 5% by weight of the polymer resin.

·         As additives to modify the surface properties of plastic films.  The new primary alcohols can be used to modify the surface properties of plastic films by migrating to the surface.  The alcohol portion of the new alcohols can modify the surface tension of plastic film, which can allow better printing with decreased amounts of corona treatment.  They can also help prevent moisture droplets from forming and creating “fogging” on the film.  The new primary alcohols can be used at levels up to 1% by weight in the polymer blend.

·         As additives to improve compatibility of polymer blends.  The new primary alcohols can be used to improve the compatibility of polymer blends.  The polyethylene portion of the product is compatible with non-polar polymers, while the alcohol portion of the product is compatible with more polar polymers.  The new primary alcohols can be used at levels up to 10% by weight in the polymer blend.

·         As an additive to improve dispersion of inorganic materials into polymer resins.  The new primary alcohols can be used to provide improved dispersion of inorganic materials into polymer resins.  The polyethylene portion of the new product is compatible with the non-polar resin, while the alcohol portion of the product interacts with the surface of the inorganic particle, which decreases the amount of agglomerates and provides improved dispersion.  The new primary alcohols can be used at levels up to 10% by weight in the coating formulation.

·         As a processing aid for plastic resins.  The long chain primary alcohols provides lower torque and...
