A composite polymer process aid is provided. The process aid includes one or more inorganic mineral fillers and one or functionalized polymers. The functionalized polymers include at least one base polymer functionalized with an epoxy, hydroxyl, β-keto ester, β-keto amide, or carboxylic acid reactive functional group. The composite polymer process aid is in the form of a plurality of individual particles. At least a portion of the individual particles include both inorganic mineral fillers and the functionalized polymers. The composite polymer modifier is formed by a process of: i) blending an aqueous solution, an aqueous dispersion, an aqueous suspension, an aqueous slurry, or a dry powder of the mineral fillers with an aqueous solution, an aqueous dispersion, an aqueous suspension or an aqueous emulsion of the functionalized polymers to form an aqueous blend, and ii) powderizing the aqueous blend to form the composite polymer process aid.

A method of reducing foamed density that results in a foamed polyvinyl chloride (PVC) component exhibiting reduced density. The foamed PVC component contains at least a PVC resin and a process aid blend. The process aid blend contains from 1 weight % to 60 weight % (based on the weight of the blend) of a functionalized process aid, and from 99 weight % to 40 weight % (based on the weight of the blend) of a non-functionalized process aid. The functionalized process aid includes at least one base polymer functionalized with a reactive epoxy, hydroxyl, β-keto ester, β-keto amide, or carboxylic acid functional group. The foamed PVC component containing the process aid blend has a lower density than a reference foamed PVC component made using the same process conditions and additives, but which contains only non-functionalized process aid and not the functionalized process aid.

The present invention relates to a composition comprising a compound with two polymerizable groups, a multistage polymer and a thermoplastic polymer its process of preparation and its use. In particular the present invention relates to a composition comprising a compound with two polymerizable groups, a multistage polymer in form of polymeric particles made by a multistage process and a (meth)acrylic polymer. More particularly the present invention relates to polymer composition comprising a compound with two polymerizable groups, polymeric particles made by a multistage process comprising at least two stages and a (meth)acrylic polymer, its method of preparation, its use for making impact modified polymer compositions, comprising thermosetting resins and compositions and articles comprising it.

A method of reducing gloss that results in a polyvinyl chloride (PVC) component that exhibits a reduced level of surface gloss; wherein, the PVC or other thermoplastic resin component comprises: a PVC resin; one or more process aids comprising at least one base polymer with one or more of the process aids being functionalized with about 0.5 wt. % to about 35 wt. % of a reactive epoxy, hydroxyl, or carboxylic acid functional group based on the total weight of the process aids; and optionally, at least one impact modifier. The PVC or other thermoplastic resin component exhibits a gloss reduction of at least 5 points measured at an angle of 85 degrees or less when compared to a similar PVC component in which the process aids are not functionalized.

Functionalized acrylic process aids used for gloss and surface finish modification

A one-pack polymer modifier containing a) at least one process aid functionalized with a reactive epoxy, hydroxyl, β-keto ester, β-keto amide or carboxylic acid functional group, b) at least one impact modifier, c) optionally, at least one mineral filler and d) optionally, at least one further additive is useful for modifying the properties of thermoplastic polymers such as PVC, including reducing the surface gloss of an article prepared from the thermoplastic polymer and improving the impact strength of such an article.
