The present invention discloses an easy-to-process, opaque and high-impact methyl methacrylate-butadiene-styrene (MBS) polymer for polyvinyl chloride (PVC) and a preparation method thereof, and relates to the technical field of preparation of PVC additives. The easy-to-process, opaque and high-impact MBS for PVC has a core-kernel-shell (three-layer) structure, and includes the following components by mass: 1-20% of core, 70-85% of kernel and 5-20% of shell. The core is a semi-hard, lightly crosslinked copolymer of a styrene (St) monomer and an acrylate monomer. The kernel is a soft, lightly crosslinked butadiene (BD)-St polymer with a low glass transition temperature. The shell is a copolymer of St, butyl acrylate and methyl methacrylate (MMA) with a high glass transition temperature. The present invention solves the problems of low impact strength and poor processing fluidity of the existing MBS for opaque PVC products.

The invention relates to a method for polymerizing acrylates using a reactor (50). Reaction heat produced in the reactor (50) is discharged via a boiling cooler (40) in that gaseous vapors produced in the reactor (50) are supplied to the boiling cooler (40), and condensed vapors are returned to the reactor (50) from the boiling cooler (40). At least one component containing acrylate is at least partly added via the boiling cooler (40) and reaches the reactor (50) via the boiling cooler (40). The invention additionally relates to a system for polymerizing an acrylate, comprising a reactor (50) and a boiling cooler (40) for discharging reaction heat produced in the reactor (50). The boiling cooler (40) has at least one filling opening (46) for supplying at least one component containing acrylate.
