US 2011/0086227 A1 · ACRYLIC RESIN COMPOSITION AND MOLDINGS IN WHICH SAID COMPOSITION IS USED

Abstract

Provided are an acrylic resin composition with which the peeling properties are improved when multi-layer sheets are formed and roll attachment is reduced, and an acrylic/polycarbonate multi-layer sheet having good environmental resistance and good producibility in which said composition is used. A terminally-modified polycarbonate resin (0.1 to 10 wt %) having terminal groups which can be represented by general formula (1): (where R1 represents an alkylene group, R2 to R8 represent hydrogen, an alkyl group, aryl group or the like, and a is an integer from 1 to 1000) is compounded with an acrylic resin to produce the acrylic resin composition, and this is molded into a multi-layer sheet by co-extrusion with polycarbonate resin.

Dependent claims

An acrylic resin composition which comprises an acrylic resin as a main component and a terminally-modified polycarbonate resin having terminal groups represented by the following general formula (1):

(In the formula (1), R1 represents an alkylene group having 1 to 20 carbon atoms and R2 to R6 represent hydrogen, an alkyl group having 1 to 10 carbon atoms, an aryl group having 6 to 12 carbon atoms or an alkenyl group having 2 to 10 carbon atoms. R7 and R8 represent hydrogen, fluorine, chlorine, bromine, iodine, an alkyl group having 1 to 10 carbon atoms, an aryl group having 6 to 12 carbon atoms, an alkenyl group having 2 to 10 carbon atoms, an alkoxy group having 1 to 5 carbon atoms or an aralkyl group having 7 to 17 carbon atoms. “a” is an integer from 1 to 1000.)
