A thermoplastic resin composition contains an aromatic polycarbonate resin (A), a graft copolymer (B) prepared by graft-polymerizing one or more vinyl-based monomers (Y) onto a rubbery polymer (X), and a (meth)acrylate-based copolymer (C) prepared by polymerizing a vinyl-based monomer mixture (m1) containing a (meth)acrylate-based monomer. In the thermoplastic resin composition, preferably, 25 to 80 parts by mass of the aromatic polycarbonate resin (A), 10 to 30 parts by mass of the graft copolymer (B), and 10 to 45 parts by mass of the (meth)acrylate-based copolymer (C) are contained, based on 100 parts by mass in total of the aromatic polycarbonate resin (A), the graft copolymer (B), and the (meth)acrylate-based copolymer (C). A thermoplastic resin-molded article is obtained by molding the thermoplastic resin composition.

A modified polysiloxane has formula (I)

##STR00001##

In formula (I) m is an integer between 0 and 10000; n is an integer between 0 and 10000; m and n cannot be equal to 0 simultaneously; R.sub.1-R.sub.7 are the same or different; and at least one of R.sub.1-R.sub.7 includes a group having a reversible chemical bond system based on a hydrogen bond, a coordinate bond, or a covalent bond. The polysioxane is used as a main chain to introduce a reversible chemical bond having temperature sensitivity by using a chemical method, so as to obtain a polymer material which is highly sensitive to temperature. The temperature-sensitive properties of materials provide functional materials for specific applications, such as medical external fixation materials, orthopedic materials, and packaging materials, can be obtained by using particular processing and preparation methods.

The invention related to a one-pot process of making a single-phase silicone-acrylic hybrid adhesive composition comprising acrylic polymer and silicone polymer that are covalently bonded through a SiOSi linkage. The acrylic polymer contains at least one hydrolyzable silane (meth)acrylic monomer or siloxane (meth)acrylic macromer. These functional moieties provide reaction sites to form SiOSi bond by reacting hydrolyzable groups in the silicone polymer in the presence of a base or acid catalyst and water. The formed covalent bonds between the two incompatible systems of silicone polymer and acrylic polymer prevents phase separation and thereby a permanent, homogeneous single-phase system is formed.
