Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
33 words
A molding blend comprising 40 to 95 volume percent of a polyamide resin having a molecular weight of at least 15000 and, complementally, 60 to 5 volume percent of an imidized acrylic resin.
Claim 2
Dependent Claim
33 words
A molding blend comprising 40 to 95 volume percent of a polyamide resin having a molecular weight of at least 15000 and, complementally, 60 to 5 volume percent of an imidized acrylic resin.
Claim 3
Dependent Claim
43 words
A molding blend according to claim 1 wherein the imidized acrylic resin contains at least 10% by weight of recurring imide units of the formula wherein R is hydrogen or hydrocarbyl of 1-20 carbon atoms, and R 1 is -CH 3 or H.
Claim 4
Dependent Claim
43 words
A molding blend according to claim 1 wherein the imidized acrylic resin contains at least 10% by weight of recurring imide units of the formula wherein R is hydrogen or hydrocarbyl of 1-20 carbon atoms, and P 1 is -CH 3 or H.
Claim 5
Dependent Claim
40 words
A molding blend according to claim 1 wherein the imidized acrylic resin is composed of recurring units of imidized methyl acrylate or imidized methyl methacrylate in which at least 40% of the recurring units of the resin are imide units.
Claim 6
Dependent Claim
33 words
A molding blend according to any one of the preceding claims, which comprises 40 to 80 volume percent of the polyamide and, complementally, amount 20 to 60 volume percent of imidized acrylic resin.
Claim 7
Dependent Claim
17 words
A molding blend according to any one of the preceding claims wherein the polyamide is polyhexamethylene adipamide.
Claim 8
Dependent Claim
26 words
Process for preparing a molded blend as claimed in any one of the preceding claims which comprises mixing the polyamide resin and the imidized acrylic resin.
Claim 9
Dependent Claim
34 words
Process for forming a shaped article of a molding blend as claimed in any one of claims 1 to 6 which comprises melting said blend, forming said shaped article, and cooling the shaped article.
