PRODUCTION OF THERMOPLASTIC POLYMER MOLDED PRODUCT HAVING MARBLE-LIKE PATTERN

摘要

PROBLEM TO BE SOLVED: To easily obtain the subject molded product having a beautiful marble- like appearance, excellent in mechanical physical properties and useful for household appliances, etc., in a wide molding temperature range by using the particles of a composition comprising specific polymers as a pattern-forming material. SOLUTION: A composition comprising (A) 60-99.0 pts.wt. of a thermoplastic polymer base material and (B) 40-0.1 pts.wt. of a pattern-forming material comprising (i) 1-95wt.% of at least one kind of crystalline thermoplastic polymer and (ii) 99-5wt.% of at least one kind of thermoplastic polymer which is different from the component (i) and has a complex viscosity coefficient [ηb ' (TM)] of 1×10<3> to 2×10<5> poises at a temperature TM is molded under temperature conditions of inequalities I and II [TM is a temperature ( deg.C) set to the cylinder of a molding machine; Tm (min) is the melting point ( deg.C) of a thermoplastic polymer having the lowest melting point in the component (i); Tm (max) is the melting point ( deg.C) of a thermoplastic polymer having the highest melting point], where the total amount of the components A and B is 100 pts.wt.
