Polymeric (meth)acrylate plasticizers and processing aids
The polymeric (meth)acrylate chains are trapped within the elastomer thereby having an enhanced permanence within the elastomer. This results in increased life to the plasticized elastomer and the ability to add more filler without bleed out of the filling material.
Polymeric (meth)acrylate plasticizers and processing aids
The polymeric compositions of the elastomer compositions of the present invention are present as interpenetrating networks of polymeric plasticizer and/or processing aids within the elastomer polymer matrix. The polymeric (meth)acrylate chains are trapped within the elastomer thereby having an enhanced permanence within the elastomer.
Hot melt extrusion: An industrially feasible approach
In this section, polymers which are mainly used in oral strip technology are discussed with special emphasis on thermal stability and extrudability. In HME process, polymer acts satisfactorily with particular plasticizers. Hence, combined discussion of polymer and plasticizer is more appropriate than that of polymer alone. 3.1.1.

- What polymers can be made with (meth)acrylic acid segments?
- This review summarizes recent advances in the design and synthesis of novel complex polymers with (meth)acrylic acid segments using various living and controlled polymerization techniques. As polymeric architectures, we will focus on block copolymers, branched polymers, Janus micelles, and polymer brushes.
- What are poly (meth)acrylates?
- Poly (meth)acrylates are synthetic (co)polymers prepared by free-radical polymerization. They exhibit extremely low batch-to-batch variations when compared to natural, raw material polymers.
- Can star polymers of (meth)acrylates be controlled?
- However, the controlled synthesis of well-defined star polymers of (meth)acrylates is not easy, because of the reduced reactivity towards multi-functional terminating agents at the low temperatures which typically must be used in order to avoid side reactions.
- Can a poly(meth)acrylate be simulated without a plasticizer?
- After confirming the suitability of the simulation model, a typical poly (meth)acrylate was simulated with and without external and internal plasticizers, using two different plasticizers with markedly different molecular structures. Simulations were used to find polymer glass transitions.
- When did poly (meth)acrylate coatings come out?
- Poly (meth)acrylate coatings for pharmaceutical applications were introduced in 1955 with the launch of EUDRAGIT ® L and EUDRAGIT ® S, two types of anionic polymers. Since then, by introducing various monomers into their polymer chains and thus altering their properties, diverse forms with specific characteristics have become available.
- Are protected monomers still required to obtain well-defined polymers with (meth)acrylic acid segments?
- Hence, protected monomers are still required to obtain well-defined polymers with (meth)acrylic acid segments.
