Abstract: PROBLEM TO BE SOLVED: To obtain the subject plastisol having excellent storage stability and low viscosity, capable of forming a film excellent in mechanical and optical properties and useful for flooring materials, floor layers or the like by compounding a specific (meth) acrylate polymer with a softener and an inorganic filler. SOLUTION: This plastisol is prepared by compounding (A) 100 pts.wt. of a (meth)acrylate (co)polymer having a weight average molecular weight more than 2,000,000 g/mol with (B) 5-400 pts.wt. of a softener compatible with the component A and (C) 9-700 pts.wt. of an inorganic filler. The component A is obtained by subjecting a monomer mixture consisting of 20-100 wt.% of methyl methacrylate (M1 ), 0-80 wt.% of a compound (M2 ) of the formula [R1 is H or methyl; R2 is a (branched) 1-18C alkyl] other than the monomer M1 , 0-40 wt.% of a monomer (M3 ) other than the monomers M1 and M7 , and 0-40 wt.% of an adhesivity imparting monomer (M4 ), wherein the total of the monomers M1 to M4 is 100 wt.%, to polymerization such as emulsion polymerization.

Abstract: Plastisol contains and acrylate polymer with molecular weight greater than 2 \* 10 g/mole and plasticiser. Plastisol comprises: (i) polymers and/or copolymers, with molecular weight greater than 2 \* 10 g/mole, of: (a) 20-100 wt.% methyl methacrylate, (b) 0-80 wt.% linear or branched 1-18 C alkyl (meth)acrylate, of formula (I), (c) 0-40 wt.% other monomer, and (d) 0-40 wt.% adhesion promoting monomer; (ii) 5-400 pts. wt. compatible plasticiser; and (iii) 9-700 pts. wt. inorganic filler. R1 = hydrogen or methyl R2 = linear or branched 1-18 C alkyl An Independent claim is also included for the use of the acrylate (co)polymer(s) in the production of plastisols.
