The present invention relates to an additive to prevent phase separation between a low profile additive and the other components of the molding composition, said other components comprising at least an unsaturated resin and an unsaturated monomer.

Additive to prevent phase separation of low profile additive in unsaturated thermoset polyester compositions

A composition comprising particulate solid, an organic medium and a dispersant comprising a polyacrylic copolymer functionalized with a polyether and reacted with an aminic polybasic species.

Multi-acid multi-base graft copolymer dispersants

The invention relates to a composition containing a particulate solid, plastic material (such as polyvinyl chloride), and a dispersant/agent comprising an oligomer from polymerizing a Chydroxycarboxylic acid optionally with a Chydroxycarboxylic acid or its corresponding lactone form.

Filled poly vinyl chloride composition

The invention relates to a composition containing a particulate solid, an organic medium, and a (meth)acrylic polymer. The invention further relates to novel compounds, and the use of the (meth)acrylic polymer as a dispersant, typically a pigment dispersant.

Dispersant composition

A composition comprising particulate solid (typically a pigment or filler), an organic medium (typically the organic medium may be a plastics material or an organic liquid) and a polyacrylic copolymer.

A composition comprising particulate solid (typically a pigment or filler), an organic medium (typically the organic medium may be a plastics material or an organic liquid) and a polyacrylic-acid-containing copolymer.

The invention relates to a composition containing a particulate solid, a plastic material (such as a thermoplastic polymer) and a compound capable of having dispersant properties. The compound may be obtained/obtainable by reacting (i) a carboxylic acid or anhydride thereof with (ii) an amine or an aminoalcohol, to form a product, wherein the carboxylic acid contains a lipophilic group R containing six or more carbon atoms; and wherein the product formed is derived from a molar ratio of (i) to (ii) is either: (a) 1:1 or greater when (i) is a carboxylic acid anhydride, or (b) ratio of greater than 1:1 when (i) is a carboxylic acid. The invention further relates to novel compounds, and the use of the compound as a dispersant.

Thermoplastic composition

The invention relates to a composition containing a particulate solid, an organic or aqueous medium, and a compound with a head group derived from phosphoric acid or sulphuric acid. The invention further relates to novel compounds, and the use of the compound as a dispersant.

The invention relates to a composition containing a particulate solid, an organic or aqueous medium, and a compound with a head group derived from phosphoric acid. The invention further relates to novel compounds, and the use of the compound as a dispersant.

Dispersants

The invention relates to a composition containing a particulate solid, a plastic material (such as a thermoplastic polymer) and a compound capable of having dispersant properties. The compound may be obtained/obtainable by reacting a fatty acid with either (i) a hydroxy-C-alkylene carboxylic acid, or (ii) a lactone. The invention further relates to novel compounds, and the use of the compound as a dispersant.

Acid endcapped caprolactone or valerolactone dispersing agents

The invention relates to a composition containing a particulate solid, a plastic material (such as a thermoplastic polymer) and a compound containing an amide group. The compound is capable of being a dispersant. The invention further relates to novel compounds, and the use of the compound as a dispersant.

A composition comprising a particulate Solid, an organic medium and a compound with an alkyleneoxy compound with an inorganic acidic polar head group (Z), wherein the compound is defined by Formula (1) and salts thereof: U&#x2014;(Y)-T-N(G)(B&#x2014;Z)(Formula 1) wherein U is independently R'&#x2014;N&#x2014;(C)-T&#x2032;-O&#x2014;, or R&#x2014;O&#x2014;; R or R&#x2032; may be the same or different and are independently H or C-optionally substituted hydrocarbyl, or hydrocarbonyl group (acyl group), or the residue of an epoxide, or the residue of an optionally substituted (meth) acrylic ester or amide group; Y is C-alkyleneoxy; T or T&#x2032; is independently Calkylene; B is an alkylene group, such as, methylene; Z is an inorganic acidic polar head group, such as, a sulphur or phosphorus acidic polar head group; G and G&#x2032; may be the same or different and are independently H or C-optionally substituted hydrocarbyl or C-optionally substituted hydrocarbyl or hydrocarbonyl group or the residue of an epoxide, or the residue of an optionally substituted (meth) acrylic ester or amide group; r is zero or 1; q is 1 or 2, with the proviso that when q is 2, r is zero; and x is from 2 to 90.

Dispersant and compositions thereof

Basic and acid dispersants derived from branched alkyl aliphatic acids and alcohols and one or more hydroxy carboxylic acid or lactone to give a polyoxyalkylenecarbonyl chain (POAC) having a terminal carboxylic acid group (TPOAC acid) or terminal hydroxy group (TPOAC alcohol). Preferred basic dispersants are obtained by reaching one or more TPOAC acids with a polyamine or polyimine such as polyethyleneimine and preferred anionic dispersants are prepared by forming a phosphate ester of a TPOAC alcohol.
