A thermoplastic resin composition comprising: (a) a polymer comprising recurring units derived from a polycyclic (meth)acrylate represented by formula [I] wherein m is 0 or a positive integer; n is 0 or 1; R is hydrogen or methyl; R1-R18 are each independently hydrogen, halogen or hydrocarbon; R15-R18 may be linked together to form a monocyclic or polycyclic group which may have a double bond; R15 and R16, or R17 and R18, may form an alkylidene group; p is 0 or 1, and when p is 1 Ra and Rb are each independently hydrogen or hydrocarbon; and (b) at least one soft polymer having a glass transition temperature (Tg) of not higher than 0°C, an intrinsic viscosity (η) as measured in decalin at 135°C of 0.01 to 10 dl/g, and a crystallinity index as measured by X-ray diffraction of 0 to 10% selected from (ii) an α-olefin polymer comprising recurring units from at least 2 α-olefins, (iii) a copolymer between an α-olefin and an acyclic non-conjugated diene or a cyclic non-conjugated diene, or a hydrogenated product thereof, and (v) a polymer or copolymer selected from polyisobutylene and a polymer of a conjugated diene, and/or (b') a soft polymer which is a graft modified copolymer of (ii) or a block copolymer obtainable by graft polymerizing (iii) or (v) with either a polycyclic (meth)acrylate of formula [I] or a monomer polymerizable with the polycyclic (meth)acrylate; in a weight ratio of (a):(b)+(b') of 99:1 to 40:60.
